string fence text properties are actually present on string delimiters before
trying to remove them.

such that an element's END element will be nil if the pertinent literal is
open at EOB.
(c-full-pp-to-literal): Before setting the aforementioned END element, check
that we're no longer in a literal. (c-literal-limits): When
c-full-pp-to-literal returns a list with a nil END element, replace this by
(point-max) to keep the interface of c-literal-limits unchanged.
* lisp/progmodes/cc-mode.el (c-after-change-mark-abnormal-strings): Having
found a string quote, check it is not inside an unterminated comment (i.e. one
at EOB).

syntax-table text properties from c-fl-syn-tab text properties for these
functions.

This is because these variables are needed at runtime even when cc-fonts.el
hasn't been loaded, as in XEmacs when font locking hasn't been enabled.
* lisp/progmodes/cc-fonts.el (c-doc-line-join-re)
(c-doc-bright-comment-start-re, c-doc-line-join-end-ch): Move definitions to
cc-mode.el.
* lisp/progmodes/cc-defs.el: (c-syntax-table-hwm): Move the defvar to here

set c-new-END to the end of logical line (which might be a long macro).
(c-after-change-mark-abnormal-strings): Calculate end-hwm in place of the
setting of c-new-END (above). Use this as a search limit rather than
c-new-END.
This variable was declared after an invocation of a defsubst which used it,
the defsubst being in another file.
* lisp/progmodes/cc-mode (c-syntax-table-hwm): Move the declaration to earlier
in the file.
* lisp/progmodes/cc-engine.el (c-truncate-lit-pos-cache): Maintain the new

(c-full-put-near-cache-entry): New functions.
(c-full-pp-to-literal): Amend to use the new functions, and to optimize the
use of the available caches, similarly to c-semi-pp-to-literal.
Make it possible to control the relative ordering of functions on hooks by
specifying `depth` in the same was as was possible with `add-function`.
* lisp/electric.el (electric--sort-post-self-insertion-hook):
Delete function.

(c-parse-quotes-after-change): Add cond arms to recognize and handle the
anomalous construct '\'. Correct the handling of c-new-BEG in

its delimiters and set c-new-BEG/END to its limits.
(c-after-change-mark-abnormal-strings): When applying syntax-table properties
to string delimiters, also set c-new-BEG/END to ensure subsequent
fontification.
* lisp/progmodes/cc-fonts.el (c-font-lock-complex-decl-prepare)
(c-font-lock-objc-methods) (c-font-lock-declarations, c-font-lock-enum-tail)

(c-set-doc-comment-res): New function.
(c-font-lock-doc-comments): For consistency and repeatability, in a sequence

Except for the important detail that it doesn't make temporary files,
the new flymake-cc backend doesn't yet behave much differently from
the old flymake-proc-legacy-flymake, i.e. it still needs a special

flags. However, the new infrastructure created should allow less
intrusive cleverer flag guessers (yet to be written) to replace that
mechanism.

* lisp/progmodes/flymake-cc.el: New file.
* lisp/progmodes/cc-mode.el (c-before-change-check-unbalanced-strings): Before
going back a sexp from the \n marked with a string-fence syntax-table text
property, check that it is indeed a \n. If not, simply delete that text
property from the isolated quote, not the quote and the \n which otherwise
delimit an unterminated string. Should we encounter a double quote marked
with a string-fence syntax-table text property at the end of the last line,
remove that property.
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.
