Let me see if I got everything correctly. Correct me if any of the
below observations are wrong.

So what's expected is an error message that details all possible errors
found in a command in a single message. Now that would be better than
what 'mv' does.

Ok, now that seems to require little work. I'll see what I could come
up with.
Before I get into this I noticed that "--set-upstream" has been
deprecated since,
b347d06bf09 (branch: deprecate --set-upstream and show help if we detect possible mistaken use,
Thu Aug 30 19:23:13 2012)
Is there any possibility for it to be removed some time in the near
future?
I'm asking this because IIRC, the 'attr_only' parameter of
"validate_new_branchname" was introduced to fix a regression
(fa7993767560) caused by the "--set-upstream" option. In case it has
been planned to be removed some time soon, it could make the word
easier (?), not sure though.

I would like to credit that to "Ævar Arnfjörð Bjarmason", who suggested
that to me in one of the other threads.
