[PATCH] Fix `git svn rebase` if top-level HEAD directory exist

[ojab]

Oh hai!
I have a svn repo with the top-level directory named HEAD and `git svn 
rebase [HEAD] [--]` fails with

$ git svn rebase
fatal: ambiguous argument 'HEAD': both revision and filename
Use '--' to separate paths from revisions, like this:
'git command [revision...] -- [file...]'
rev-list --first-parent --pretty=medium HEAD: command returned error: 128


Works fine with patch in the attached file. please review.

This rationale should probably go in the commit message.


Done



We prefer patches to be inline in the email; these lines can be
dropped, as they are picked up from your email headers.


AFAIK Thunderbird brakes spaces, so better safe, than sorry :)


Do you mind providing a real name? The point of Signed-off-by is for
licensing and attribution.


Done (but i doubt that such a patch can be copyrighted).


Looks obviously correct to me. I did a quick grep, and there is one
other spot that probably should get the same treatment:


Yep, already found it.
