Re: [RFC] Variable substitution in gtags.conf

Hi. Yamaguchi san.

 In thre current implementation, "gtags --config=name" expands  variables, but "gtags --config" does not.
Is this an intention?

$ gtags --config=gtags_parser
fortran:/home/iwamoto/global/lib/gtags/exuberant-ctags.la,pascal:/home/iwamoto/global/lib/gtags/exuberant-ctags.la,c#:/home/iwamoto/global/lib/gtags/exuberant-ctags.la,lisp:/home/iwamoto/global/lib/gtags/exuberant-ctags.la,scheme:/home/iwamoto/global/lib/gtags/exuberant-ctags.la,awk:/home/iwamoto/global/lib/gtags/exuberant-ctags.la,ruby:/home/iwamoto/global/lib/gtags/exuberant-ctags.la,perl:/home/iwamoto/global/lib/gtags/exuberant-ctags.la,python:/home/iwamoto/global/lib/gtags/exuberant-ctags.la,vim:/home/iwamoto/global/lib/gtags/exuberant-ctags.la,sh:/home/iwamoto/global/lib/gtags/exuberant-ctags.la
