If GTAGS is not found under $PWD or its ancestors, it should fail.
Since it is a fundamental specification of GLOBAL, it is hard to change it.
At such time, you should use GTAGSROOT environment variable, I think.

        $ mkdir nullproject             # make null project
        $ cd nullproject
        $ gtags
        $ pwd
        /home/you/nullproject

        $ GTAGSROOT=/home/you/nullproject global -x ...

But if your idea means that global -c should read GTAGSs in $GTAGSLIBPATH
if no matched tag name is found in the GTAGS under $PWD or its ancestors,
it might be useful. That is consistent.
