I wonder if we should check that the committer identity is unchanged as
well in case anyone is using this to fix commits after committing with
the wrong identity.

I think that if you reword a commit committed by someone else but end
up with no changes I want it to be kept as it was.

That depends on the reason why the feature to "reword" the commit is
being used, and the use case Phillip is talking about is a bit
different.

So the answer is "it depends". Maybe we should do handle this the same
as git-commit(1) does with its "--reset-author" flag?
