Fabian Homborg c20187e858 completions/git: Stop offering :/ files so much
Don't do it when the relative path is simple (purely descending),
unless the token starts with ":/".

Also stop offering directories - if they need to be disambiguated, the
normal completion logic will take care of that.

Fixes #5574.
