Re: [PATCH] checkout: Don't crash when switching away from an invalid branch.

For that matter, dying without removing the trace of that funny state
might be even preferrable if you need to do postmortem to figure out why
you got into such a funny state to begin with, but not everybody uses git
to debug git.

It turns out to be user error, that was a tree I hadn't used in a long
time and I didn't realize it was using alternates, so HEAD was pointing
to a commit that had been rebased and garbage-collected in the source
repository.

Most other commands die with a "bad object HEAD" in that situation, and
checkout could certainly do that too, but I think it's nicer to provide
an easy way of getting out of that broken state.  I'll resend an updated
patch.
