histedit: don't crash if commit message is empty

Summary

If the commit message is empty, histedit will crash before this patch
because it assumes that summary.splitlines() is non-empty. One of
our users at work ran into this crash for a commit that was created by
an internal system.

I don't think we have a good way of testing this because it's hard to
create a commit with an empty commit message. I've added a comment to
help prevent regressions.
