c-block-stmt-hangon-key.

commit/cc-mode: acm: Replace faulty non-matching regexp "\\<\\>" with
"a\\`"

Summary: Replace faulty non-matching regexp "\\<\\>" with "a\\`"
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\\`".
* cc-defs.el (cc-fix, c-make-keywords-re)
* cc-engine.el (c-beginning-of-statement-1, c-forward-<>-arglist-recur)
(c-forward-decl-or-cast-1, c-looking-at-decl-block)
* cc-fix.el (top-level)
* cc-langs.el (c-assignment-op-regexp, c-block-comment-ender-regexp)
(c-block-comment-start-regexp, c-line-comment-start-regexp)
(c-doc-comment-start-regexp, c-decl-start-colon-kwd-re)
(c-type-decl-prefix-key, c-type-decl-operator-prefix-key)
(c-pre-id-bracelist-key, c-enum-clause-introduction-re)
(c-nonlabel-token-2-key)
* cc-vars.el (c-noise-macro-with-parens-name-re, c-make-noise-macro-regexps):
Replace "\\<\\>" by "a\\`".

* simple.el (no-case-regexp-p):
* simple.el (with-search-caps-disable-folding):
* simple.el (with-interactive-search-caps-disable-folding):
* simple.el (log-message-filter):
Use `string-match-p' in these functions, no need to save the match
data with same.
* simple.el (clone-process):
* simple.el (clone-buffer):
* simple.el (clone-indirect-buffer):
Ditto; use the same idiom throughout the file when stripping
trailing <DIGIT+> patterns from strings.
