In git
there is a command git commit --amend
to edit one's last commit message (among other things). I was looking for this type of functionality in PyCharm and can't seem to find it.
When file changes are being added to an amended commit, the Commit Changes dialog shows a Amend commit checkbox, but I find no obvious way to amend only the commit message. (I can trick the checkbox into showing up by selecting a file, checking the Amend commit box, and then unselecting the file, but the Commit button is greyed out.)
Google turns up "How to edit a commit message in PyCharm?" but it was not answered satisfactorily (or perhaps it's not applicable to the current version?). The help page linked to in the previous question does not provide the answer, nor have I been able to find it in the rest of the docs. (Per meta.stack* suggestion I attempted to update the existing, unanswered question, but my edits were rejected.)
Further review turns up "Using IntelliJ to amend git commit message", a couple years old and without an accepted answer, and since PyCharm is based on IDEA, possibly applicable.
Is this even possible in PyCharm 4.5.3?
