'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.
