273	Strings are immutable in Python, so it wasn't actually replaced, right? Or do I misunderstand your concern?

Spotted in a later patch, need to replace _ back to - before printing output.

Strings are immutable in Python, so it wasn't actually replaced, right? Or do I misunderstand your concern?

Maybe he meant opts[b'dry_run'] vs --dry-run. *args should follow
underscore naming, but the printed option names don't.

Yep what Yuya said. Spotted in D7644, test-rebase-obsolete.t, line 490.

Oh, I would consider that a bug in that patch (I would have used dry-run if I had noticed). However, I can see how you would prefer that we pass in the underscore-separated name (since that's what we do with indexing into opts). I was concerned that there were existing flags that were underscore-separated in the UI, but there doesn't seem to be any (I checked by running the test suite with a hacked fancyopts.py). So I'll switch to using the underscore-separated names in the API.

Nit: better to return the unique argument in the original format, not
the dash-ed version.
