while thinking about what to write, i came up with an idea for another
improvement: with (implicit) --edit, the template message would end up
being:

 This reverts commit <sha1>,
 because <PUT REASON HERE>.

+DISCUSSION
+----------
+
+While git creates a basic commit message automatically, you really
+should not leave it at that. In particular, it is _strongly_
+recommended to explain why the original commit is being reverted.
+Repeatedly reverting reversions yields increasingly unwieldy
+commit subjects; latest when you arrive at 'Reapply "Reapply
+"<original subject>""' you should get creative.
