b619777dd6 Allow a CC Mode derived mode to have strings delimited by single quotes.
Also fix the bug where the delimiters of '\033', etc. got the error face.

* lisp/progmodes/cc-langs.el (c-single-quotes-quote-strings): Enhance the docr
string.
(c-string-delims): Change doc string to doc comment.

* listp/progmodes/cc-mode.el (c-before-change-check-unbalanced-strings): In
searches and comparisons, take account of the string delimiters possibly
being '.  Fix argument in call of c-before-change-check-unbalanced-strings.
(c-parse-quotes-before-change, c-parse-quotes-after-change): Bind
case-fold-search to nil.  Analyze escape constructs inside character constants
more accurately, in particular accepting as valid more than one character
after /[0-7], /x, /u, and /U.  Amend calculations to account for this extra
length.

bb591f139f Enhance CC Mode's fontification, etc., of unterminated strings.
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)

a718e1593a Fix some errors in c-display-defun-name when the type is "struct {..}", etc.
Also fix some errors with c-display-defun-name when there are nested classes.

* lisp/progmodes/cc-cmds.el (c-in-function-trailer-p): Deal with a struct {..}
being merely the type of a function.
(c-where-wrt-brace-construct): Deal with a struct {..} being merely the type
of a function.  Rearrange the order of some Lisp forms.  Insert a check for
c-protection-key ("private", etc.) alongside the checking for a label.
(c-defun-name-1): New function extracted form c-defun-name, which works within
the existing restriction.  Don't regard 'at-function-end as being within the
defun any more.  Recognize "struct", etc., with the new
c-defun-type-name-decl-key rather than c-type-prefix-key.  Make the
recognition of a normal function more accurate.
(c-defun-name): Part left after extracting the above function.  It now just
widens and calls c-defun-name-1.
(c-declaration-limits-1): New function extracted from c-declaration-limits,
which works within the existing restriction.  Move LIM back one block to
account for the possibility of struct {..} as a function type.  Check we're
not inside a declaration without braces.
(c-declaration-limits): Part left after extracting the above function.  It now
just narrows to an enclosing decl block and calls c-declaration-limits-1.
(c-defun-name-and-limits): New function which identifies the name and limits
of the most nested enclosing declaration or macro.
(c-display-defun-name): Use c-defun-name-and-limits rather than two separate
functions (which didn't always agree on which function).

* lisp/progmodes/cc-engine.el (c-beginning-of-statement-1): If we have struct
{..} as the type of a function, go back over this, too.

* lisp/progmodes/cc-langs.el (c-defun-type-name-decl-kwds)
(c-defun-type-name-decl-key): New lang const/var.

immediately after the "(" or following a comma.
(c-looking-at-inexpr-block): Test c-has-compound-literals rather than hard
coded C++ Mode.

bc511a64f6 Prefer HTTPS to FTP and HTTP in documentation
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.

c417f08b16 Correctly fontify C++ direct initializations with parens inside functions
Or, more clearly, when something looks like a function declaration and it's
inside a function, fontify it as a direct initialization.

For this purpose, introduce a "brace stack" for each buffer, where an entry on
the brace stack states how deeply nested a particular position is inside
braces inside a "top level", which includes classes and namespaces.

Also introduce a new "context", "top", with which c-font-lock-declarations
signals to c-forward-decl-or-cast-1 that point is at the top level.

* lisp/progmodes/cc-langs.el (c-get-state-before-change-functions): add
c-truncate-bs-cache.
(c-flat-decl-block-kwds, c-brace-stack-thing-key, c-brace-stack-no-semi-key)

* lisp/progmodes/cc-engine.el (c-bs-interval, c-bs-cache, c-bs-cache-limit)
(c-bs-prev-pos, c-bs-prev-stack): New mostly local variables for the brace
stack cache.
(c-init-bs-cache, c-truncate-bs-cache, c-truncate-bs-cache, c-brace-stack-at)
(c-bs-at-toplevel-p): New functions which manipulate the brace stack (cache).
(c-find-decl-prefix-search): Keep track of whether we're at top level.
(c-find-decl-spots): New local variable cfd-top-level which records what it
says.  On calling cfd-fun, pass cfd-top-level as an additional argument.
(c-forward-declarator): Add new element DECORATED to the result list.  Set it
to non-nil when a match for c-type-decl-operator-prefix-key is found.
(c-forward-decl-or-cast-1): Handle the newly introduced context "top".
Introduce "CASE 9.5", which recognizes direct initializations.

* lisp/progmodes/cc-fonts.el (c-font-lock-complex-decl-prepare)
(c-font-lock-enum-tail, c-font-lock-cut-off-declarators)
(c-font-lock-enclosing-decls, c-simple-decl-matchers, c-basic-matchers-after):

(c-font-lock-declarators): Additional parameter `not-top'.  Use not-top to
participate in the decision whether to fontify an identifier as a function or
a variable.
(c-font-lock-declarations): The internal lambda function takes an additional
argument `toplev' from c-find-decl-spots, which it uses in determining the
"context" of a declaration.  Add appropriate `not-top' argument to calls to
c-font-lock-declarators.
(c-font-lock-objc-methods): Add extra parameter to internal lambda function,
like for c-font-lock-declarators.

80dcc23709 Rationalize the use of c-new-BEG and c-new-END in CC Mode.
Remove the now redundant c-old-BOM and c-old-EOM.

* lisp/progmodes/cc-engine.el (c-macro-cache-syntactic): Change and simplify
meaning.
(c-macro-cache-no-comment): New variable.
(c-invalidate-macro-cache, c-beginning-of-macro, c-end-of-macro): incorporate
the new c-macro-cache-no-comment.
(c-syntactic-end-of-macro): Make better use of c-macro-cache-syntactic.
(c-no-comment-end-of-macro): New function.

* lisp/progmodes/cc-langs.el (c-before-font-lock-functions): Add
c-extend-font-lock-region-for-macros to C/C++/ObjC value.

* lisp/progmodes/cc-mode.el (c-old-BOM, c-old-EOM): Remove.
(c-extend-region-for-CPP): Put results in c-new-BEG/END rather than
c-old-BOM/EOM.
(c-extend-font-lock-region-for-macros): Simplify meaning, no longer returning
a cons for the new region, since the function is now called as an after-change
function.  No longer adjust c-new-END for the length of inserted/deleted
text.  Move the size restrictions on macros to here from
c-neutralize-syntax-in-and-mark-CPP.
(c-neutralize-syntax-in-and-mark-CPP): No longer adjust c-new-BEG/END here.
Use c-no-comment-end-of-macro rather than c-syntactic-end-of-macro to find the
upper boundary to "neutralize" syntactically obtrusive characters.
(c-change-expand-fl-region): Don't set c-new-END to next BOL when already at
one.
