Log Message:
Update global to 6.5.4.

Version 6.5.4 - Mar 27 2016

This is a bug fix release.

[CHANGES]
Changed:
o gtags.conf: The entries which include '.xml' were commented out,
  because they require libxml.a. If you use them, please uncomment them.

[FIXED BUGS]
Serious bug:
o universal-ctags.la: Universal ctags plug-in parser did not work
  on almost files. Now it works.

	$ echo 'void a() {}' >a.inl
	$ echo 'void b() {}' >b.cpp
	$ gtags --gtagslabel=new-ctags
	$ global -x '.*'
	a                   1 a.inl            void a() {}
	(b.cpp is ignored.)

Version 6.5.3 - Mar 18 2016

[CHANGES]
New facilities:
o Added new plug-in parser 'universal-ctags.la'.
o gtags.conf:
  - Added new entry 'universal-ctags'.
  - Added new variable 'ctagscom'. You can overwrite the path of ctags(1)
    dynamically for exuberant-ctags.la, universal-ctags.la and pygments-parser.la.

Changed:
o gtags.conf: Added the following patterns to the skip list.
  '*.o,*.a,*.so,*.lo,*.zip,*.gz,*.bz2,*.xz,*.lzh,*.Z,*.tgz,*.min.js,*min.css'
o gtags: Added some explanations for the --explain option.

[FIXED BUGS]
o global: Global generated incorrect path with the --color option.
  Now, it works well.

        [bad case]
	+- GTAGS
	+- hi/
	    |- foo.cpp
	    +- what/

	$ cd hi/what
	$ global -P hi/foo.cpp --color
	foo.cpp         # It should be '../foo.cpp'.

o global: Global aborted in obstack_free() in some cases. Now it works well.
o htags: Htags ended abnormally when there is a file which includes single
  quote characters in its file name. Now, it works.
