f19b9165 (merge-ort: convert more error() cases to path_msg(),
2024-06-19) is what I have, date is different (and object name is,
too, obviously).

And funny thing is that your base-commit points at the latter.  I
briefly wondered if we can somehow automate the generation of
reference in the log message, but the base is likely to be the tip
of the topic branch that has been accepted upstream, and the commit
being fixed up can be something below, not at, that tip, so it
wouldn't be like a simple and silly "compare base-commit and the
commit we talk about in the proposed log message".

A commit-msg hook that scans for names that look like commit object names in the
message, and

 - makes sure that these commits are reachable from HEAD (the goal
   is to make sure they are reachable from the resulting commit),
   and possibly

 - makes sure that these commits are reachable from @{u} (the goal
   is to catch references of unpublished commits)

might be a possibility, but such criteria are probably highly
workflow specific, so needs to be highly customizable if we wanted
to make such a feature as a part of what we ship.

Thanks.  I saw Peff's earlier message and the change exactly matches
my expectation.  Will queue (with adjustments to the log message).
