Odd error when doing "clone && cd && checkout -b"

Odd error when doing "clone && cd && checkout -b"

[Jacob Helwig]

In talking with someone in the IRC channel, I ran across something that
I thought was very odd behavior.  I'm sure there's a very simple
explanation, but I can't think of what it might be.

The person was getting "fatal: git checkout: updating paths is
incompatible with switching branches.", when they tried to create a new
tracking branch, and switch to it, with a fresh clone.  I was able to
reproduce this, but only by one-lining the "clone && cd && checkout -b".

When the "checkout -b" fails from the one-lined version, immediately
doing the "checkout -b" on its own succeeds.

The output below is from zsh (4.3.10), however I get the exact same
behavior when I run the commands using bash (4.0.33).  I was testing
this using Git 1.6.6.1.598.g661e2.

== One-lined Version ==

Did you intend to checkout 'origin/permissions-rewrite' which can not be resolved as commit?

Or did you intend to track 'origin/permission-rewrite' instead ;-)

Well, I _thought_ I had used the exact same command for the "checkout
-b".  Obviously, this is not the case.  Bah.  That's what I get for
trying to do anything so late.

Apparently Mutt defaults to setting the Mail-Followup-To, if you've let
it know about a list.  Anyway...that's been fixed.
