Some power user workflow requires `uncommit` to leave an empty commit so they can run `hg amend` afterwards. I don't find easy alternatives so let's allow that if `ui.allowemptyconfig` is set. Note: `ui.allowemptyconfig` is an internal config that is not documented for end-users. Core Mercurial seems to be trying to prevent the empty commit case from normal users (like, comment disallows that, rebase will skip a commit if after rebasing it becomes empty). So it seems better to still use that undocumented config instead of a more discoverable flag. Differential Revision: https://phab.mercurial-scm.org/D156
