(Python_functions, PHP_functions): Name tags, for ctags' sake.
(TeX_commands): Name tags. Correction of old disabled code.
* etags.c (curfiledir, curtagfname): New global variables.
(process_file): Initialise them.
(readline): Canonicalize the name found in #line directive.

compilers that don't optimize out dead code.

(no_line_directive): New global var; set it for old behaviour.
(main): Remove some #ifdef in the getopt switch.
(add_node, put_entries): Code added to merge different chunks of
nodes referring to the same file. Currently the tags are just
appended, without any check for duplicates.
(Perl_functions): Do not special case ctags.
(readline): Identify #line directives and do the right thing.
(nocharno, invalidcharno): New global vars.
(process_file): Reset nocharno.
(readline): Set nocharno.
(pfnote): Read nocharno and maybe put invalidcharno in node.
(total_size_of_entries, put_entries): Use invalidcharno.
* etags.c: Keep the whole tag table in memory, even in etags mode.
(main): Call put_entries here even in CTAGS mode.
(main, process_file): Check the return values of fclose and pclose.
(process_file): Do not call put_entries after parsing each file.
(process_file): Canonicalise file names even for ctags.
(process_file): Set curfile here...
(find_entries): ... not here any more.
(add_node): In etags mode, build a linked list of entries (on
right pointer) for each file, and link the first entry of each
file on left nodes.
(put_entries): Print here the name of the file.
(put_entries): Print the entries starting from the first file.
(number_len, total_size_of_entries): Define these only iin etags
mode, make the second work only on the right nodes.
* etags.c: Make all global variables static.

(AWK, TMPDIR): Work around portability problem in broken shells that
don't understand `: ${VAR=val}'.
(SORT_K_OPTIONS): New var, for hosts that conform to POSIX 1003.1-2001.
Prefer the new -k option to the traditional +M -N option.

(get_tag): Return a pointer to the tag that is found.
general cleanup and streamlining
* etags.c (LOOKING_AT): Use !intoken instead of iswhite.

modified LOOKING_AT.
(notinname): Removed '[' and added ')' to the recognised chars.
(LOOKING_AT, get_tag, PHP_functions): Use notinname.

(L_isdef, L_isquote): Removed.
(Lisp_functions, L_getit): Clarified.
changes for standalone compilation
* etags.c: (P_): Renamed to __P for consistency with config.h.
[HAVE_CONFIG_H]: Let config.h deal with __P.
[__STDC__] [!HAVE_CONFIG_H]: Define PTR as in config.h.
[!__STDC__] [!HAVE_CONFIG_H]: Do not undefine static, because
gperf code needs it.

[HAVE_CONFIG_H] [!__P]: Define __P (for use with Xemacs).
(xmalloc, xrealloc): Use PTR instead of long *.
