Right, will fix.

Yeah I agree this is a bit odd.  I did think about this, and the main
reason why I didn't change this by passing the '--quiet' flag to 'git
branch' which we call in the 'add()' function is to keep the
information about the remote tracking.

Looking at where this information actually comes from, there's
multiple different ways we'd have to distinguish to print this
information properly.

Now that I put some more thought into this, I think there are a couple
of ways to solve this, the easiest and cleanest of which would
probably be to run 'git branch' through 'pipe_command', save the
output and print it after the "creating branch 'foo'" message.

Tbh I never really noticed the "Checking out files" output, because
the repositories I used day to day are usually of a smaller size,
where checking out the files takes less than a second, so I would
never even notice this output.

But while I don't care about it, others may, so I think it would be
better to preserve this output.  Maybe the best way to do that would
be to not use 'run_command' to run 'git reset --hard', but to instead
replace that with the internal functions.

I haven't actually looked at how hard this would be, but I'm guessing
this may be the best option to avoid this UI regression.  I'll play
with this some more and see what I can come up with, and send a
re-roll hopefully in a few days.

Thanks for your review!
