pathspec completion missing in Bash completion

[Björn Kautler <Bjoern@xxxxxxxxxxx>]

Hi,

if you use bash completion, pathspecs are not completed with existing
paths with 2.40.0.
So if you for example do `git add -- :^<TAB><TAB>` or `git add --
:^a<TAB><TAB>` you do not get any suggestions, though it would make
sense to complete the paths there.

Regards
Björn
