          This method uses the ``hg remove --after`` to match the semantics of
          ``git commit --all`` (which is _not_ the same as ``hg commit
          --addremove``) however ``hg remove --after`` is _very_ verbose (it
          comments on every existing file in the repository) and it ignores the
          ``--quiet`` option. This explains why I've decided to silence the
          standard error stream (though I feel I may regret this later).
