I'm not sure we still need old behavior. Anyway, I think we could
"emulate" it without code changing, just by setting GTAGSROOT
environment variable.

In the 'gtags.vim', we could write something like this note:

" Global will search for it's tag databases starting from the current file's 
path upwards.
" If you need precise database location, set GTAGSROOT environment variable to 
it's path directory before you start Vim or in your vimrc file.
" If there no files opened, the search is started from current directory.
"
"       :e /project1/subdir/lib.c
"       :Gtags main                     <- from now on, search 
/project1/subdir, /project1, / for GTAGS.
"       :e /project2/main.c
"       :Gtags main                     <- from now on, search /project2, / for 
GTAGS.
