Message-ID: <20140407131911.GB17654@ixro-vdogaru.ixiacom.com>

```
'git p4 rebase' fails with the following message if there is a file
named HEAD in the current directory:

	fatal: ambiguous argument 'HEAD': both revision and filename
	Use '--' to separate paths from revisions, like this:
	'git <command> [<revision>...] -- [<file>...]'

Take the suggestion above and explicitly state that HEAD should be
treated as a revision.

This looks obviously good to me, thanks!

Junio, could you carry it into the next release?  As a trivial
fixup.
