Re: Bug in git rebase -i where <upstream> is "HEAD" in 1.5.4?

   I've discovered a difference in behavior between `git rebase` and
`git rebase -i`, and I believe the behavior exhibited by `git rebase -
i` is incorrect and should be changed to match `git rebase`. The
behavior difference occurs when running the command in the form:

git rebase [-i] <upstream> <branch>

   If <upstream> is "HEAD", `git rebase` seems to perform these
(correct) steps:

A=$(git rev-parse HEAD)
git checkout <branch>
git rebase $A

Yes, I remember writing that side carefully, taking exactly this
issue into account.

   However, `git rebase -i` seems to perform these (incorrect) steps:

Yeah, I see that interactive side is sloppier.  In
git-rebase--interactive.sh, if you move

        HEAD=$(git rev-parse --verify HEAD) || die "No HEAD?"
        UPSTREAM=$(git rev-parse --verify "$1") || die "Invalid base"

around l.481 up so that they come before if test !  -z "$2",
you would be Ok, although I didn't test it.
