All right.

git-prompt.sh is not really part of the completion stuff, so I don't
think the location Debian chose is correct. At some point in time they
were together, so perhaps that why they chose the same location.

Generally scripts and other shared data belongs in /usr/share.

Probably because it was split from 'git'.

Yes, we would need --share-path, and perhaps GIT_SHARE_PATH, and so on.

Might make sense for a future patch.
