I split this up and will have a re-submission of it soon.

Let's discard it for now, I was looking it at today hoping to re-roll it
and saw that it some of the changes would be a hassle for
me/you to manage with other things I have in-flight.

So I'll either submit it after that, or another version which doesn't
textually/semantically conflict like that, but in any case let's drop
this version.

Will re-roll this soon. Need to get to addressing your outstanding

FWIW I commented a bit on the status just now in another thread here:

And, just to add to your note, also the back & forth thread about the
need/design for the new refspec.c API here:

I think so, it's trivial :)

FWIW to your suggestion of completion instead checking *_HEAD: As part
of another (abandoned for now) topic of mine I tried to exhaustively
enumerate all the magic all-caps refs just the test suite generates in
.git/FILE, and it's quite a big list.

So I found listing a new known one less scary.

Also, even though the bash completion is pretty bad about it now, I
thinkw we should aim more for it not needing to hit disk for completing
a thing like "git show REBASE_HE<TAB>" (which it'll needlessly do now).

Thanks. FWIW I kept hacking on send-email a bit, and have some local
patches that bring the runtime of from 30 seconds to
13, and a typical invocation time for git-send-email from ~250ms on my
box to ~40-60ms).

Please :)

But perhaps Jeff King would like to look it over first...

FWIW it seems it's now past that per and this note
was added before that update to the thread.

I know you know that, just noting that for the benefit of others who are
following along.

I'd like that, some of the ORT code is over my head currently, but
having it tested by default would be very beneficial to smoke out any
bugs sooner than later.
