Summary: Fix ＠examples in cc-mode.info, where lines were getting glued together.
This happened because of false ＠c's in macro lines.
* cc-mode.texi (Line-up Functions): Remove the unneeded ＠c from macros
sssTBasicOffset, sssTsssTBasicOffset, and hereFn.

commit/cc-mode: acm: Fix some errors in c-display-defun-name when the

Summary: 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.
* 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).
* cc-engine.el (c-beginning-of-statement-1): If we have struct {..} as the
type of a function, go back over this, too.
* cc-langs.el (c-defun-type-name-decl-kwds, c-defun-type-name-decl-key): New
lang const/var.

Summary: Handle C99 Compound Literals in return statements and argument lists.
* cc-engine.el (c-looking-at-or-maybe-in-bracelist): Recognize a brace list
when preceded by "return" or inside parentheses, either immediately after the
"(" or following a comma.
(c-looking-at-inexpr-block): Test c-has-compound-literals rather than hard
coded C++ Mode.
(c-guess-basic-syntax, CASE 7B): Test additionally for not being just inside a
parenthesis or being at a Java "new" keyword. CASE 9: Remove the simple
minded test on the contents of a block to determine a brace list.
* cc-langs.el (c-has-compound-literals): New lang const and lang var.

Summary: C++ Mode: Fontify correctly uniform initialisation with inner parentheses.
E.g.: someStruct x ( (nullptr != y) ? 3 : 4 )
Also fontify declarations of function pointers correctly.
* cc-engine.el (c-forward-decl-or-cast-1): While testing for a typeless
declaration, additionally test the variable `got-prefix' to recognize a
function pointer in parentheses. Allow c-fdoc-shift-type-backward to be
invoked when we have nested parens.
