* lisp/progmodes/cc-cmds.el (c-electric-lt-gt): Actuate electric-pair-mode if
a < or > is typed in a context where this is meaningful (#include, or
template).
(c-electric-paren): Allow electric-pair-mode activity in a comment or string.
* lisp/progmodes/cc-defs.el (c-make-keywords-re): Fix a bug where lists of
source symbols could get overwritten when parameter adorn is set to
'appendable.
* list/progmodes/cc-langs.el (c-cpp-include-key): New lang const and var.
* lisp/progmodes/cc-cmds.el, lisp/progmodes/cc-defs.el
lisp/progmodes/cc-engine.el, lisp/progmodes/cc-fonts.el
lisp/progmodes/cc-langs.el: Add lots of edebug specs.
* lisp/progmodes/cc-engine.el (c-state-maybe-marker): Tidy up so as to
evaluate an argument only once at runtime.
I audited use of lsh in the Lisp source code, and fixed the
glitches that I found. While I was at it, I replaced uses of lsh
with ash when either will do. Replacement is OK when either
argument is known to be nonnegative, or when only the low-order
bits of the result matter, and is a (minor) win since ash is a bit
more solid than lsh nowadays, and is a bit faster.
* lisp/calc/calc-ext.el (math-check-fixnum):
Prefer most-positive-fixnum to (lsh -1 -1).
* lisp/vc/vc-hg.el (vc-hg-state-fast): When testing fixnum width,
prefer (zerop (ash most-positive-fixnum -32)) to (zerop (lsh -1
32)) (Bug#32485#11).
* lisp/emacs-lisp/bytecomp.el (byte-compile-lapcode):
Tighten sanity-check for bytecode overflow, by checking that the
result of (ash pc -8) is nonnegative. Formerly this check was not
needed since lsh was used and the number overflowed differently.
* lisp/net/dns.el (dns-write): Fix some obvious sign typos in
shift counts. Evidently this part of the code has never been
exercised.
* lisp/progmodes/hideif.el (hif-shiftleft, hif-shiftright):

String delimiters, including escaped new lines, of correctly terminated
strings are left in font-lock-string-face. All others get
font-lock-warning-face. The latter get syntax-table text properties on the
opening string delim and the "terminating EOL".
Correct two miscellaneous bugs: the handling of text properties on Java Mode's
generic delimiters; the handling of c-just-done-before-change.
* lisp/progmodes/cc-defs.el (c-point): New position 'eoll "end of logical line".
(c-characterp): New macro.
* lisp/progmodes/cc-fonts.el (c-font-lock-invalid-string): Removed.
(c-basic-matchers-before): Use a simple matcher in place of the form around
c-font-lock-invalid-string.
* lisp/progmodes/cc-langs.el (c-get-state-before-change-functions): Add
c-before-change-check-unbalanced-strings to the value for all modes except AWK
Mode. Also add c-before-change-check-<>-operators to Java Mode, correcting an
error in that mode's handling of generic delimiters.
(c-before-font-lock-functions): Add c-after-change-re-mark-unbalanced-strings
to the value for all modes except AWK Mode.
(c-single-quotes-quote-strings, c-string-delims): New lang variables for
future enhancements.
(c-string-innards-re-alist): New lang variable.
* lisp/progmodes/cc-mode.el (c-just-done-before-change): Do not set this
variable when a change is the alteration of text properties.
(c-basic-common-init): Set parse-sexp-lookup-properties (and the XEmacs
equivalent) also for Pike Mode.
(c-neutralize-CPP-line): No longer neutralize unbalanced quotes here.
(c-unescaped-nls-in-string-p, c-multiline-string-start-is-being-detached)
(c-pps-to-string-delim, c-before-change-check-unbalanced-strings)
(c-after-change-re-mark-unbalanced-strings): New functions.
(c-after-change): Fix a bug with the handling of c-just-done-before-change.
The regexp "\\<\\>", which is supposed never to match, actually matches, for
instance, where a Chinese character is directly followed by an ASCII letter.
So, replace it with "a\\`".

* lisp/progmodes/cc-vars.el (c-noise-macro-with-parens-name-re)
(c-make-noise-macro-regexps):
Replace "\\<\\>" by "a\\`".
Do this by removing a broken optimization in the state cache which put
category text properties on a character between the end of the CPP construct
and the beginning of the comment. This can't work when there's no such
character.
* lisp/progmodes/cc-defs.el (c-cpp-delimiter, c-set-cpp-delimiters)
(c-clear-cpp-delimiters, c-comment-out-cpps, c-with-cpps-commented-out)
(c-with-all-but-one-cpps-commented-out): Remove.
* lisp/progmodes/cc-engine.el (c-no-comment-end-of-macro): Return the comment
start position rather than one character before it.
(c-invalidate-state-cache, c-parse-state): Remove the invocations of
c-with-all-but-one-cpps-commented-out and c-with-cpps-commented-out.
* lisp/progmodes/cc-mode.el (c-neutralize-syntax-in-and-mark-CPP): Rename to
c-neutralize-syntax-in-CPP and remove the bits which applied category
properties.
* lisp/progmodes/cc-langs.el (c-before-font-lock-functions): Incorporate the
new name of the function c-neutralize-syntax-in-CPP.
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.
* lisp/progmodes/cc-defs.el
(c-search-forward-char-property-with-value-on-char): New macro.
* lisp/progmodes/cc-mode.el (c-parse-quotes-before-change)
(c-parse-quotes-after-change): Rewrite the functions, simplifying
considerably, and removing unnecessary optimisations. Invalidate two caches
after manipulating text properties.
* lisp/progmodes/cc-defs.el (c-set-keymap-parent): New macro.
* lisp/progmodes/cc-mode.el (top-level): Remove cc-bytecomp-defun for
set-keymap-parents.
(c-make-inherited-keymap): Use c-set-keymap-parent in place of inline code.
Single quotes, even in strings and comments, are now marked with the
"punctuation" syntax-table property, except where they are validly bounding a
character literal. They are font locked with font-lock-warning-face except
where they are valid. This is done in C, C++, ObjC, and Java Modes.
* lisp/progmodes/cc-defs.el (c-clear-char-property-with-value-on-char-function)
(c-clear-char-property-with-value-on-char, c-put-char-properties-on-char): New
functions/macros.
* lisp/progmodes/cc-fonts.el (c-font-lock-invalid-single-quotes): New function.
(c-basic-matchers-before): invoke c-font-lock-invalid-single-quotes.
* lisp/progmodes/cc-langs.el (c-get-state-before-change-functions): Remove
c-before-after-change-digit-quote from wherever it occurs. Insert
c-parse-quotes-before-change into the entries for the languages where it is
needed.
(c-before-font-lock-functions): Remove c-before-after-change-digit-quote from
wherever it occurs. Insert c-parse-quotes-after-change into the entries for
the languages which need it.
(c-has-quoted-numbers): New lang-defconst/-defvar.
* lisp/progmodes/cc-mode.el (c-before-after-change-digit-quote): Remove.
(c-maybe-quoted-number-head, c-maybe-quoted-number-tail)

variable.

(Top level): Amend the form which requires library cl or cl-lib.
(c--mapcan, c--set-difference, c--intersection, c--macroexpand-all)
(c--delete-duplicate): Amend to use c--cl-library instead of
c--mapcan-status.
* lisp/progmodes/cc-engine.el (c-syntactic-skip-backward)
(c-back-over-compound-identifier): Remove unused local variables.
* lisp/progmodes/cc-fonts.el (c-font-lock-declarations): Remove an unused
local variable.
* lisp/progmodes/cc-langs.el (Top level): Amend to use c--cl-library instead
of c--mapcan-status.
* lisp/progmodes/cc-styles.el (Top level): Add a cc-bytecomp-defun to try to
silence a compiler warning.
Cache c-state-semi-nonlit-pos-cache was failing when a cache position was,
e.g., between the two characters of an opening comment "/*", and additionally
there were an odd number of quote marks (apostrophes) in the comment. This
happened in .../src/xdisp.c in the Emacs master branch around 2017-05-02 at
buffer position 615001.
* lisp/progmodes/cc-defs.el (c-emacs-features): Repurpose symbol
pps-extended-state to mean that there are at least 11 elements in the parser
state.
* lisp/progmodes/cc-engine.el (c-cache-to-parse-ps-state)
(c-parse-ps-state-to-cache): Rewrite these to use enhanced cache element list
types which indicate potentially being inside two-char constructs.
(c-parse-ps-state-below): Rewrite to use the new versions of the above two
functions.

not identically nil before generating a narrow-to-region call. Generate code

(c--macroexpand-all): Check macroexpand-all directly rather than
c--mapcan-status.
This patch should not change behavior. It typically omits backslashes
where they are redundant (e.g., in the string literal "^\$").
In a few places, insert backslashes where they make regular
expressions clearer: e.g., replace "^\*" (equivalent to "^*") with
"^\\*", which has the same effect as a regular expression.
Also, use ‘\ %’ instead of ‘\%’ when avoiding confusion with SCCS IDs,
and similarly use ‘\ $’ instead of ‘\$’ when avoiding confusion with
RCS IDs, as that makes it clearer that the backslash is intended.
This also eliminates `mapcan' warnings in XEmacs.
progmodes/cc-defs.el (c--mapcan-status): new variable to characterise
[X]Emacs versions.
(top-level): Require either 'cl or 'cl-lib, depending on
c--mapcan-status.
Change this back to cc-external-require from an eval-when-compile
require.
(c--mapcan, c--set-difference, c--intersection, c--macroexpand-all)
(c--delete-duplicates): New macros which expand into either old or new
names.
(c-make-keywords-re, c-lang-defconst, c-lang-const) Use the new macros
rather than the old names.
progmodes/cc-engine.el (c-declare-lang-variables): Use c--mapcan rather
than mapcan.

The main change is to only use the `category' text-property only when
available. For that many calls are changed to use c-get-char-property,
c-next-single-property-change, c-sc-scan-lists,
c-sc-parse-partial-sexp, c-unmark-<->-as-paren.

Handle the case where categories are not available.
(c-record-parse-state-state, c-replay-parse-state-state):
Handle marker values.
(c-before-change-check-<>-operators): Look for the `syntax-table'
property rather than for the corresponding `category'.
