Re: [PATCH 2/2] rebase -i: new option --name-rev

On a general note: you are submitting a completely new feature touching
a heavily-used tool (and code path) during -rc0 time.  As a rule of
thumb: Don't do that.  If you do it, don't Cc Junio unless it's his area
of code.

Hum.  I'm not sure yet if I find that very useful, since frequently the
names will just be 'topic', 'topic~1', ...., 'topic~N' if you are
rebasing a topic with N+1 commits not in master.  But you might, so who
am I to judge.

The --no- version is implicitly always supported, see gitcli(1).

You should spell it in a more readable way such as
rebase.interactiveNameRev.  The config machinery internally downcases
everything so the cosmetics won't prevent it from working.

In the spirit of your previous patch, wouldn't it be faster to run 'git
name-rev --stdin' within the pipeline?

How does this interact with --autosquash?

In line with the --autosquash concern, please write a test that uses
both option (and verifies that *both* work!).
