I guess that's because you're using reflog syntax and pulling up a
commit that isn't on the current branch, due to rebasing, resetting,
or any such activity.  Using the reflog syntax, for the few commits I
tried, produced the desired result.

I'm not sure why you'd use reflogs, however, as I believe the
--max-age or --since parameters to rev-list seem to be more in line
with your request.  Actually, I'd be surprised if you couldn't
identify the one commit that you wanted to use and use it directly;
the rev-list was just to show an example.

Thank you,
