Really? I didn't see it mentioned in your commit message, which
consisted entirely of:

  t: mailmap: add 'git blame -e' tests

Yes, I know you mentioned it elsewhere in the thread. But review should
happen on what is actually in the posted patch. That is what reviewers
are guaranteed to have read, and it is what people reading "git log" in
a year will see. If there was other discussion or context that led to
the patch, it's helpful in both cases to summarize it.

Are there already git-blame tests, but not "blame -e" tests? If there
are already "blame" tests, why do we additionally need "blame -e" tests?

I can guess, or I can do my own digging in the history to find out, but
that makes review a lot more painful. You already did the digging and
came to understand the problem when you made your patch. Why not just
share it?

Sorry, that should have been s/mailmap/blame/ above. But if I am making
wrong assumptions about the rationale, then isn't that a sign that the
commit message is insufficient?

Yes, I think you did describe the "what", which in this case is very
simple. But as I mentioned before, it is not just knowing the "what" but
evaluating that the "what" meets the "why" from step 1.

I don't necessarily assume the worst. If I were the maintainer, I might
even have taken your patch as-is, as it's pretty simple. But I found a
description like the one Jonathan included to be _much_ easier to
review. Whether yours was above a minimum threshold or not, I think it's
worth striving to be better.
