[PATCH 02/10] submodule deinit: lose requirement for giving '.'

The discussion in [1] realized that '.' is a faulty suggestion as
there is a corner case where it fails:

"submodule deinit ." may have "worked" in the sense that you would
have at least one path in your tree and avoided this "nothing
matches" most of the time.  It would have still failed with the
exactly same error if run in an empty repository, i.e.

       $ E=/var/tmp/x/empty && rm -fr "$E" && mkdir -p "$E" && cd "$E"
       $ git init
       $ rungit v2.6.6 submodule deinit .
       error: pathspec '.' did not match any file(s) known to git.
       Did you forget to 'git add'?
       $ >file && git add file
       $ rungit v2.6.6 submodule deinit .
       $ echo $?
       0

There is no need to update the documentation as it did not describe the
special case '.' to remove all submodules.
