The completion helper for index paths uses git ls-files rather than shell
filename completion. As a result, leading-dot paths such as a tracked
.gitignore were offered even when the user had not started the path with ..

Hide leading-dot path components for git rm, git mv, and git ls-files when
completing an empty path component. Explicit dot completion is still
preserved, so git rm . can still complete .gitignore.

This removes the existing TODO expectations in t/t9902-completion.sh and
adds coverage for explicit dot completion.

Validation:

 * git diff --check -- contrib/completion/git-completion.bash
   t/t9902-completion.sh
 * bash -n contrib/completion/git-completion.bash
 * ./t9902-completion.sh

Zakariyah Ali (2):
  completion: hide dotfiles for selected path completion
  completion: hide dotfiles by default for path completion
