global doesn't respect functions declared as static

In C source, I have defined two static functions in separate files. When I
search for definition of one of these, I sometimes get the wrong location.

What I did:
global -d my_func --from-here "133:/path/to/src/my-source.c"

Result I got:
src/my-first-source.c
src/my-source.c

As I have given --from-here argument, it should be showing only the definition
from the same file (as the function is declared static).

Expected result:
src/my-source.c


Alternatly, if it is hard to track the return type of functions, the result
can be sorted that the first item shown is from the same file (when there is a
match).

Ie, The result then would be:
src/my-source.c
src/my-first-source.c


Note: I have been using ggtags in GNU Emacs. Looking into source, I see this is
ggtags is doing. So I think, the first result is what that matters the most.

Thanks
