Exactly what I wanted. Thank you very much.

Just one more thing : 
If I use `gtags /tmp/gtagsdb`, global gives path like
"../../../tmp/gtagsdb/YYY/include/file.h"

It would be nice to use absolute path in a such case (eg when GTAGS is
not in the root) and display "/usr/YYY/include/file.h". 
Ok, I can use a symbolic link, so it is not very annoying.
