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.

	* etags.c: (C_entries): In case '}' decrement bracelev before testing it.

	* etags.c (C_entries): In case '}', set fvdef to fvnone
	unconditioned to (!ignoreindent && lp == newlb.buffer + 1).

	* etags.c: (C_entries): Reset the fvdef machine when out of function.
	(C_entries): Parse start of C comment as a space == end of token.
	This is not necessary for C++ comment, already parsed as newline.

Remove Ken Arnold copyright.
(print_version): Remove Ken Arnold, refer to new file ETAGS.README.

(main): Now --members is the default for etags, not for ctags yet.

The previous change introduced 2004-09-13 was broken, as (C_JAVA &
!C_PLPL) always evaluates to 0.  This caused import, package, extends,
implements and interface to be treated specially for all kinds of
C-style files, not just Java files. (by Per Cederqvist).

(no_duplicates): Static variables for the above option.
(print_help): Do not print help for --no-warn, now undocumented.
(add_node): Allow duplicate tags in ctags mode unless --no-duplicates.

#line directive, leave the file name alone.  The previous
behaviour was to make it relative to the tags file directory,
under the hypothesis that the #line directive file name was
relative to the directory of the tagged file.  That hypothesis is
wrong with Cpp and Lex.

(Makefile_targets): Do not include spaces in tag names.

(readline): Check for double quote after #line.
(readline): sscanf could in principle return 2.
(TeX_commands): Use p++ (rather than *p++) to increment p.
(Lua_functions): Explicitely discard LOOKING_AT's return value.
(TEX_mode): Check getc retruns EOF.
	    File ended without newline causes infinite loop.

 File ended without newline causes infinite loop.

It's XEmacs, not Xemacs: change all the occurences.

[ETAGS_REGEXPS]: Now is unconditionally defined.
[LONG_OPTIONS]: Changed to NO_LONG_OPTIONS, which is undefined.
(Objc_suffixes): Suggest using --lang=c for full help.
(C_entries): Initialise savetoken to 0 to shut up the compiler.

(in_word_set): In C, also tag #undef symbols.

(Erlang_functions): Possibly free space allocated for var last.
(Prolog_functions): Possibly free space allocated for var last.

which has never been opened.

Specify in the --help that vgrind writes to stdout.

(prolog_pr): Cast strlen to int before comparison.
(LOOKING_AT, LOOKING_AT_NOCASE): Let the preprocessor check that
the second argument is indeed a literal string.
(longopts, print_help, main): The -a (--append) option
can be used in ctags also; for one, the Linux make file uses it.

preprocessing to compile time constant.

default targets to silence compiler.

make them relative to the current working dir, rather than
relative to the output tags file, if the latter is in /dev.
