Log Message:
Updated global to 6.5.7.

Version 6.5.7 - 15 May 2016

[CHANGES]
o global: Now global(1) accept a file as --nearness option.
  If it is a file, tags in the file are shown first.
o global: Added aliases for MAKEOBJDIR and MAKEOBJDIRPREFIX.
  GTAGSOBJDIR: alias for MAKEOBJDIR
  GTAGSOBJDIRPREFIX: alias for MAKEOBJDIRPREFIX
  These aliases are given higher priority than the originals.
o global: New command --print=<name>.
  <name> may be one of: root, dbpath or conf.
  This is a generic version of the -p (--print-dbpath) command.
	'global -p' is equal to 'global --print=dbpath'
	'global -pr' is equal to 'global --print=root'
o gtags: Updated the built-in PHP parser to support namespaces and traits,
  which were introduced in PHP5. The following keywords have been removed:
	- failure: not a keyword
	- header: normal built-in function
	- is_array: normal built-in function
	- is_set: typo -> isset
	- printf: normal built-in function
	- setcookie: normal built-in function
	- success: not a keyword

[FIXED BUGS]
o globash: Echo command with -n option didn't work on some OS. Now it works.
o global: The --nearness option without -x option brought segmentation fault.
	$ global --nearness=. main
	Segmentation fault: 11
  Now it works.
o global: --from-here with -i option did not ignore case of function name
  in the context. Now it works.
	Input:
	[main.c]
	1: main() {
	2:         func();
	3:         Func();
	4: }
	5: func() {}
	6: Func() {}

	$ global -xi --from-here=6:main.c func
	(global-6.5.6)
	Func                6 main.c           Func() {}
	func                5 main.c           func() {}
	(global-6.5.7)
	Func                3 main.c            Func();
	func                2 main.c            func();

[INCOMPATIBLE CHANGES]
o gtags.conf: Added new candidate path.
        (1) --gtagsconf file
        (2) $GTAGSCONF
        (3) [project root]/gtags.conf
        (4) [project root]/[objdir]/gtags.conf       <- [NEW]
        (5) $HOME/.globalrc
        (6) /etc/gtags.conf
        (7) [sysconfdir]/gtags.conf

        The default of [objdir] is 'obj'. You can change it by
        the environment variables (GTAGSOBJDIR or MAKEOBJDIR).
