It seems this would make it easier to change the value of the plugin
path by consolidating them in one place. i.e. it is an improvement.

I wonder if it can be made even better without leaking the plugin path
to user's configuration file (.globalrc). So instead of

   :gtags_parser=c\:/usr/local/unix/global/lib/gtags/user-custom.la:
   :gtags_parser=Asm\:/usr/local/unix/global/lib/gtags/exuberant-ctags.la:

we write:

   :gtags_parser=user-custom:
   :gtags_parser=exuberant-ctags:

Leave the job to `global', `gtags' and whatnot to figure out where to
find it. What do you think?

Thanks,
