Comment 4 for bug 507529

Tom: If you noticed the typo right after the commit, then the hard uncommit & recommit workflow as outlined above would have solved the issue. If it's to late for that, then the request here won't help you either, as it really only requests a more ergonomical frontend to the above workflow.

You might want to have a look at bug #210142 instead, which seems better suited for situations like the one you describe.
