Subject: (default_C_help) [CTAGS]: differentiate the help string,
X-Git-Tag: emacs-pretest-22.1.90~330
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=f96732e5b794b1683e79339314d341606c325d3f;p=emacs.git

(default_C_help) [CTAGS]: differentiate the help string,
as the defaults in ctags are different from etags.
(default_C_help, Cplusplus_help, PHP_help, print_help): Remove
text saying --members is the default: not true in Emacs 22.
