Numbers with a trailing dot and an exponent were incorrectly read as
integers (with the exponent ignored) instead of the floats they should
be. For example, 1.e6 was read as the integer 1, not 1000000.0 as
every sane person would agree was meant. (Bug#48678)
Numbers with a trailing dot but no exponent are still read as
integers.

That commit did not make the corresponding change to printing, thus
breaking the (eq (read (prin1-to-string SYM)) SYM) invariant for those

behavior, therefore revert the reader change.

Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
* src/lread.c (read1): Signal an error when a symbol starts with a
non-escaped quote-like character.
* test/src/lread-tests.el (lread-tests--funny-quote-symbols): New
test.
* etc/NEWS: Announce change.
Without this fix, (substitute-object-in-subtree #0=(#0# 'a) 'a)
would dump core, since the C code would recurse indefinitely through
the infinite structure. This patch adds an argument to the function,
and renames it to lread--substitute-object-in-subtree as the function
is not general-purpose and should not be relied on by outside code.
See Bug#23660.
* src/intervals.c (traverse_intervals_noorder): ARG is now void *,
not Lisp_Object, so that callers need not cons unnecessarily.
All callers changed. Also, remove related #if-0 code that was
“temporary” in the early 1990s and has not been compilable for
some time.
* src/lread.c (struct subst): New type, for substitution closure data.
(seen_list): Remove this static var, as this info is now part of
struct subst. All uses removed.
(Flread__substitute_object_in_subtree): Rename from
Fsubstitute_object_in_subtree, and give it a 3rd arg so that it
doesn’t dump core when called from the top level with an
already-cyclic structure. All callers changed.
(SUBSTITUTE): Remove. All callers expanded and then simplified.
(substitute_object_recurse): Take a single argument SUBST rather
than a pair OBJECT and PLACEHOLDER, so that its address can be
passed around as part of a closure; this avoids the need for an
AUTO_CONS call. All callers changed. If the COMPLETED component
is t, treat every subobject as potentially circular.
(substitute_in_interval): Take a struct subst * rather than a
Lisp_Object, for the closure data. All callers changed.
* test/src/lread-tests.el (lread-lread--substitute-object-in-subtree):
New test, to check that the core dump does not reoccur.
* src/lread.c (load_warn_old_style_backquotes, Fload, read1)
(syms_of_lread): Rename `old-style-backquotes' to
`lread--old-style-backquotes', and clarify that it's for internal
use only.
* lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Rename
variable.
* test/src/lread-tests.el (lread-tests--old-style-backquotes): Add
unit test.
* emacs-lisp/bytecomp-tests.el
(bytecomp-tests--old-style-backquotes): Add unit test.
This test fails in my local machine because the data files
are compiled, and the test doesn't expect that.
* test/src/lread-tests.el (lread-test-bug26837): Match a suffix
ending with '.elc' when the data files are compiled.
* src/lread.c (readevalloop): Fix the "whole buffer" check to
operate in the correct buffer.
(Feval_buffer): Move point back to the start after checking
for lexical binding.
* test/src/lread-tests.el (lread-test-bug26837): New test.
* test/data/somelib.el, test/data/somelib2.el: New test data files.
* src/lread.c (load_warn_unescaped_character_literals, Fload, read1)
(syms_of_lread): Warn if unescaped character literals are
found (Bug#20152).
* lisp/emacs-lisp/bytecomp.el (byte-compile-from-buffer): Check for
unescaped character literals during byte compilation.
* test/src/lread-tests.el (lread-tests--unescaped-char-literals): New
unit test.
(lread-tests--with-temp-file, lread-tests--last-message): Helper
functions for unit test.
* test/lisp/emacs-lisp/bytecomp-tests.el
(bytecomp-tests--unescaped-char-literals): New unit test.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--with-temp-file):
Helper macro for unit test.
See Bug#25120.
* src/lread.c (read_integer): Treat incomplete integer literals as errors.
* test/src/lread-tests.el (lread-empty-int-literal): New unit test for
incomplete integer literals.
This also fixes the mishandling of "\N{CJK COMPATIBILITY
IDEOGRAPH-F900}", "\N{VARIATION SELECTOR-1}", etc.

* doc/lispref/nonascii.texi (Character Codes), etc/NEWS: Document this.
* lisp/international/mule-cmds.el (char-from-name): New function.
(read-char-by-name): Use it. Document that "BED" is treated as
a name, not as a hexadecimal number. Reject out-of-range integers,
floating-point numbers, and strings with trailing junk.
* src/lread.c (character_name_to_code): Call char-from-name
instead of inspecting ucs-names directly, so that we handle
computed names like "VARIATION SELECTOR-1". Do not use an auto
string, since char-from-name might GC.
* test/src/lread-tests.el: Add tests for new behavior, and
fix some old tests that were wrong.
* doc/lispref/nonascii.texi (Character Properties):
Avoid duplication of Unicode names. Reformat examples to fit in
narrow pages.
* doc/lispref/objects.texi (General Escape Syntax):
Simplify and better-organize explanation of \N{...} escapes.
* src/character.h (CHAR_SURROGATE_PAIR_P): Remove; unused.
(char_surrogate_p): New inline function.
* src/lread.c: Do not include string.h; no longer needed.
(invalid_character_name, check_scalar_value): Remove; the ideas
behind these functions are now bundled into character_name_to_code.
(character_name_to_code): Remove undocumented support for "CJK
IDEOGRAPH-XXXX" names, as "U+XXXX" suffices. Reject monstrosities
like "\N{U+-0}" and null bytes in \N escapes. Reject floating
point in \N escapes instead of returning garbage. Use
AUTO_STRING_WITH_LEN to lessen pressure on the garbage collector.
* test/src/lread-tests.el (lread-char-number, lread-char-name)
(lread-string-char-number, lread-string-char-name):
Test runtime behavior, not compile-time, as the test framework
is not set up to test compile-time.
(lread-char-surrogate-1, lread-char-surrogate-2)
(lread-char-surrogate-3, lread-char-surrogate-4)
(lread-string-char-number-2, lread-string-char-number-3):
New tests.
(lread-string-char-number-1): Rename from lread-string-char-number.
* lread.c (invalid_character_name, check_scalar_value)
(parse_code_after_prefix, character_name_to_code): New helper
functions that use 'ucs-names' and parsing for CJK ideographs.
(read_escape): Use helper functions.
(syms_of_lread): New symbol 'ucs-names'.
* test/src/lread-tests.el: New tests; fix a couple of bugs in
existing tests.
* lread.c (init_character_names): New function.
(read_escape): Read Perl-style named character escape sequences.
(syms_of_lread): Initialize new variable 'character_names'.
* test/src/lread-tests.el (lread-char-empty-name): Add test file
for src/lread.c.
