This fixes some infinite loops that cannot be quitted out of,
e.g., (defun foo () (nth most-positive-fixnum '#1=(1 . #1#)))
when byte-compiled and when run under X. See:
http://lists.gnu.org/archive/html/emacs-devel/2017-01/msg00577.html
This also attempts to keep the performance improvements I recently
added, as much as possible under the constraint that the infloops
must be caught. In some cases this fixes infloop bugs recently
introduced when I removed immediate_quit.
* src/alloc.c (Fmake_list):
Use rarely_quit, not maybe_quit, for speed in the usual case.
* src/bytecode.c (exec_byte_code):
* src/editfns.c (Fcompare_buffer_substrings):
* src/fns.c (Fnthcdr):
* src/syntax.c (scan_words, skip_chars, skip_syntaxes)
(Fbackward_prefix_chars):
Use rarely_quit so that users can C-g out of long loops.
* src/callproc.c (call_process_cleanup, call_process):
* src/fileio.c (read_non_regular, Finsert_file_contents):
* src/indent.c (compute_motion):
* src/syntax.c (scan_words, Fforward_comment):
Remove now-unnecessary maybe_quit calls.
* src/callproc.c (call_process):
* src/doc.c (get_doc_string, Fsnarf_documentation):
* src/fileio.c (Fcopy_file, read_non_regular, Finsert_file_contents):
* src/lread.c (safe_to_load_version):
* src/sysdep.c (system_process_attributes) [GNU_LINUX]:
Use emacs_read_quit instead of emacs_read in places where
C-g handling is safe.
* src/eval.c (maybe_quit): Move comment here from lisp.h.
* src/fileio.c (Fcopy_file, e_write):
Use emacs_write_quit instead of emacs_write_sig in places where
C-g handling is safe.
* src/filelock.c (create_lock_file): Use emacs_write, not
plain write, as emacs_write no longer has a problem.
(read_lock_data): Use emacs_read, not read, as emacs_read
no longer has a problem.
* src/fns.c (rarely_quit): Move to lisp.h and rename to
incr_rarely_quit. All uses changed..
* src/fns.c (Fmemq, Fmemql, Fassq, Frassq, Fplist_put, Fplist_member):
* src/indent.c (compute_motion):
* src/syntax.c (find_defun_start, back_comment, forw_comment)
(Fforward_comment, scan_lists, scan_sexps_forward):
Use incr_rarely_quit so that users can C-g out of long loops.
* src/fns.c (Fnconc): Move incr_rarely_quit call to within
inner loop, so that it catches C-g there too.
* src/keyboard.c (tty_read_avail_input): Remove commented-out
and now-obsolete code dealing with interrupts.
* src/lisp.h (rarely_quit, incr_rarely_quit): New functions,
the latter moved here from fns.c and renamed from rarely_quit.
(emacs_read_quit, emacs_write_quit): New decls.
* src/search.c (find_newline, search_buffer, find_newline1):
Add maybe_quit to catch C-g.
* src/sysdep.c (get_child_status): Always invoke maybe_quit
if interruptible, so that the caller need not bother.
(emacs_nointr_read, emacs_read_quit, emacs_write_quit):
New functions.
(emacs_read): Rewrite in terms of emacs_nointr_read.
Do not handle C-g or signals; that is now for emacs_read_quit.
(emacs_full_write): Replace PROCESS_SIGNALS two-way arg
with INTERRUPTIBLE three-way arg. All uses changed.
* doc/misc/htmlfontify.texi (Interactive):
* lisp/htmlfontify.el (htmlfontify-buffer):
Spell out character names, for clarity. The old doc string
generated the *Help* text ‘^L ([FF]) or ¤ (244)’, where ‘[FF]’
stands for a form feed character; this was confusing.
* lisp/electric.el (electric-quote-mode):
* src/doc.c (syms_of_doc):
* src/editfns.c (Fformat_message):
Remove no-longer-necessary ‘\=’s in doc strings.
* lisp/cus-edit.el (custom-buffer-create-internal):
* lisp/recentf.el (recentf-edit-list):
Follow text-quoting-style preference when quoting in UI strings.
* src/doc.c (Fsubstitute_command_keys): Don’t say that curved
quotes are substituted for, as this is no longer true.
* src/doc.c (Fsubstitute_command_keys): Fix some problems with
unibyte strings and with buffer allocation. Make strings
multibyte, to avoid problems with unibyte strings that are not
valid UTF-8 (Bug#24206). Redo buffer allocation so that it is
O(N), not O(N**2). Avoid going past the end of the input string
when given invalid input. Avoid some unlikely problems in
accessing the wrong storage after a GC.
This fixes a five-year-old FIXME comment. Although I don’t know
of a platform where this is a problem in practice, better safe
than sorry.
* src/doc.c (Fdocumentation): If SUBRP, simply use doc as integer,
as it is now an integer, not char *.
(store_function_docstring): Offset is now EMACS_INT, not ptrdiff_t;
this is a file offset and EMACS_INT is better if --with-wide-int.
If SUBRP, simply store the offset rather than negating it and
converting it to char *.
* src/lisp.h (struct Lisp_Subr.doc): Now EMACS_INT, not char *.
Change 'text-quoting-style' so that it no longer affects
formatting of curved quotes in format arguments to functions like
'message'. In particular, when this variable's value is 'grave',
all quotes in formats are output as-is.

when text-quoting-style is `leave'.
* src/lisp.h (enum text_quoting_style): Add identifier LEAVE_QUOTING_STYLE.
* src/doc.c (syms_of_doc): New symbol "leave". Amend doc string of
`text_quoting_style'.
(text_quoting_style): Handle `leave' by returning LEAVE_QUOTING_STYLE.
(Fsubstitute_command_keys): Don't translate quotes when quoting_style is
LEAVE_QUOTING_STYLE.
* src/editfns.c (styled_format): Set quoting_style to -1 when
text-quoting-style is `leave'.
Problem reported by Clément Pit--Claudel (Bug#23254).
* src/doc.c: Include intervals.h.
(Fsubstitute_command_keys): If the only substitutions are for
quotes, copy the source string’s text properties too, since no
substring lengths have changed.

Although \( is needed in docstrings in Elisp code, it is not needed in
docstrings in C code, since C function definitiions do not start with
a parenthesis. The backslashes made the docstrings a bit harder to
read and to format in columns. Also, some C docstrings had ( in
column 1 and this did not appear to be causing any problems. So,
simplify C docstrings by replacing \( with ( and \) with ).
This removes the need for GCPRO1 etc. Suggested by Stefan Monnier in:

This is simpler and easier to explain, and should encourage better
typography. Do this in Electric Quote mode and when translating

This is a followup to the recent doc string change, and deals with
diagnostics and the like. This patch is more conservative than
the doc string change, in that the behavior of ‘format’ changes
only if its first arg contains curved quotes and the user prefers
straight or grave quotes. (Come to think of it, perhaps we should
be similarly conservative with doc strings too, but that can wait.)
The upside of this conservatism is that existing usage is almost
surely unaffected. The downside is that we'll eventually have to
change Emacs's format strings to use curved quotes in places where
the user might want curved quotes, but that's a simple and
mechanical translation that I'm willing to do later. (Bug#21222)

If ‘ is not displayable, transliterate it to `, not to '. See:
http://lists.gnu.org/archive/html/emacs-devel/2015-06/msg00542.html
Fix several problems with the recently-added custom variable
help-quote-translation where the code would quote inconsistently
in help buffers. Add support for quoting 'like this', which
is common in other GNU programs in ASCII environments. Change
help-quote-translation to use more mnemonic values: values are now the
initial quoting char, e.g., (setq help-quote-translation ?`) gets the
traditional Emacs help-buffer quoting style `like this'. Change the
default behavior of substitute-command-keys to match what's done in
set-locale-environment, i.e., quote ‘like this’ if displayable,
'like this' otherwise.
* doc/lispref/help.texi (Keys in Documentation): Document
new behavior of substitute-command-keys, and document
help-quote-translation.
* doc/lispref/tips.texi (Documentation Tips):
Mention the effect of help-quote-translation.
* etc/NEWS: Mention new behavior of substitute-command-keys,
and merge help-quote-translation news into it.
When talking about doc strings, mention new ways to type quotes.

(LEFT_SINGLE_QUOTATION_MARK, uLSQM0, uLSQM1, uLSQM2, uRSQM0)
(uRSQM1, uRSQM2, LSQM, RSQM): New constants.
(Fsubstitute_command_keys): Document and implement new behavior.
(Vhelp_quote_translation): Document new behavior.
src/doc.c (traditional, prefer-unicode): new symbols.
(help-quote-translation): new variable.
(Fsubstitute_command_keys): make translation of quotes dependent on
`help-quote-translation'; also translate curly quotes back to ASCII
ones.
lisp/cus-start.el (top-level): Add a customization entry for
`help-quote-translation'.
Also, be more consistent about calls to 'Fmessage' vs 'message'.
* src/alloc.c (Fgc_status):
Prefer AUTO_STRING to build_string for Fmessage call.
* src/data.c (Fmake_variable_buffer_local)
(Fmake_local_variable, Fmake_variable_frame_local):
* src/doc.c (store_function_docstring):
Use Fmessage, not message, since the argument can contain
non-ASCII characters, and this can cause the resulting message
to be incorrectly encoded for the current environment.
* src/fns.c (maybe_resize_hash_table):
* src/xselect.c (x_clipboard_manager_save_all):
Use message, not Fmessage, since Fmessage's power isn't needed here.
* src/process.c (Fmake_network_process): Reword message to avoid %s.
* src/xdisp.c (vmessage): Document restrictions on message contents.
(message_nolog) [false]: Remove unused code.
So, for example, it turns "`abc'" into "‘abc’" (Bug#20385).
* doc/lispref/help.texi (Keys in Documentation):
* etc/NEWS: Document this.
* src/doc.c (Fsubstitute_command_keys): Implement it.
Fixes Bug#15880.
This patch also makes Q constants (e.g., Qnil) constant addresses
from the C point of view.
* make-docfile.c: Revamp to generate table of symbols, too.
Include <stdbool.h>.
(xstrdup): New function.
(main): Don't process the same file twice.
(SYMBOL): New constant in enum global_type.
(struct symbol): Turn 'value' member into a union, either v.value
for int or v.svalue for string. All uses changed.
(add_global): New arg svalue, which overrides value, so that globals
can have a string value.
(close_emacs_global): New arg num_symbols; all uses changed.
Output lispsym decl.
(write_globals): Output symbol globals too. Output more
ATTRIBUTE_CONST, now that Qnil etc. are C constants.
Output defsym_name table.
(scan_c_file): Move most of guts into ...
(scan_c_stream): ... new function. Scan for DEFSYMs and
record symbols found. Don't read past EOF if file doesn't
end in newline.

Remove Q vars that represent symbols (e.g., Qnil, Qt, Qemacs).
These names are now defined automatically by make-docfile.
* alloc.c (init_symbol): New function.
(Fmake_symbol): Use it.
(c_symbol_p): New function.
(valid_lisp_object_p, purecopy): Use it.
* alloc.c (marked_pinned_symbols):
Use make_lisp_symbol instead of make_lisp_ptr.
(garbage_collect_1): Mark lispsym symbols.
(CHECK_ALLOCATED_AND_LIVE_SYMBOL): New macro.
(mark_object): Use it.
(sweep_symbols): Sweep lispsym symbols.
(symbol_uses_obj): New function.
(which_symbols): Use it. Work for lispsym symbols, too.
(init_alloc_once): Initialize Vpurify_flag here; no need to wait,
since Qt's address is already known now.
(syms_of_alloc): Add lispsym count to symbols_consed.
* buffer.c (init_buffer_once): Compare to Qnil, not to make_number (0),
when testing whether storage is all bits zero.

* keyboard.c (scroll_bar_parts, struct event_head):
* xdisp.c (struct props):
Use XSYMBOL_INIT (Qfoo) and struct Lisp_Symbol * rather than &Qfoo and
Lisp_Object *, since Qfoo is no longer an object whose address can be
taken. All uses changed.
* eval.c (run_hook): New function. Most uses of Frun_hooks changed to
use it, so that they no longer need to take the address of a Lisp sym.
(syms_of_eval): Don't use DEFSYM on Vrun_hooks, as it's a variable.
* frame.c (syms_of_frame): Add defsyms for the frame_parms table.
* keyboard.c (syms_of_keyboard): Don't DEFSYM Qmenu_bar here.
DEFSYM Qdeactivate_mark before the corresponding var.
* keymap.c (syms_of_keymap): Use DEFSYM for Qmenu_bar and Qmode_line
instead of interning their symbols; this avoids duplicates.
(LISP_INITIALLY, TAG_PTR)
(DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END, XSYMBOL_INIT):
New macros.
(LISP_INITIALLY_ZERO): Use it.
(enum symbol_interned, enum symbol_redirect, struct Lisp_Symbol)
(EXFUN, DEFUN_ARGS_MANY, DEFUN_ARGS_UNEVALLED, DEFUN_ARGS_*):
Move decls up, to avoid forward uses. Include globals.h earlier, too.

(DEFSYM): Now just a placeholder for make-docfile.
* lread.c (DEFINE_SYMBOLS): Define, for globals.h.
(intern_sym): New function, with body taken from old intern_driver.
(intern_driver): Use it. Last arg is now Lisp integer, not ptrdiff_t.
All uses changed.
(define_symbol): New function.
(init_obarray): Define the C symbols taken from lispsym.
Use plain DEFSYM for Qt and Qnil.
* syntax.c (init_syntax_once): No need to worry about
Qchar_table_extra_slots.
