Right. My argument is that the context in your third point was always
intended to be about command-line options. Respecting the log.date
config there is a bug (and not just in breaking intent; it also breaks
scriptability). It was fixed for the regular pretty-print code path, but
was broken again when the "%gd" code path was added.

If that is the case (and I haven't checked either way, but it does not
surprise me at all), then I believe that is a separate bug. And we
should fix that, too.

That will solve the problem for stash, but the config bug would remain
for every _other_ user of "git log -g --format=%gd". So that needs fixed
either way.
However, I really wonder if this is the right thing. If I do:
git stash list --date=relative
isn't it a feature that I get to see the date at which each stash was
made? Why are we taking it away? I can see if it were the only way to
fix the problem with log.date, but that has another solution. Are people
really calling "stash list" with a date on the command line and getting
confused by the output? My understanding was that the observed problem
was purely a bad interaction with log.date, which should not be
respected at all.
