Introduce a leading ':' as the notation for repo-wide pathspecs.

This is in line with our treeish:path notation which defaults to repowide paths.

Heck: Even ':./path' works for pathspecs, and I have no clue why!

I have not tested this for adverse side effects, only for the intended ones
with "git grep".

It's an alternative to "--full-tree", more far reaching, maybe too far. But we seem to accept that paths do not start with ':', and that notation should make msys happy, but what do I know about msys.

(one could stick this into prefix_path() rather than get_pathspec(), but that would be way too far)
