    completion: hide dotfiles for selected path completion
    
    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 ..

Writing 'path with ".".' would have been easieer to grok.

    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.

I am not sure why this is a good idea.  If we said "git rm g<TAB>
and offered ".gitignore" as a candidate, it may be annoying, but
tracked (or untracked for that matter) ".gitignore" and "gitfoo"
should be treated the same way by "git rm <TAB>" no?

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

In any case, all of the above should be in the proposed log message,
not below the three-dash line.
