Commit Message

`unshelve` was using HEAD^$n to find the parent commit. This meant that
any intervening commits between HEAD and the last git-p4 commit would
cause the unshelve to fail.

e.g.
    123ab Local git-only commit
    234bc Another local git-only commit
    345cd Perforce tip revision

Unshelve needs to find 345cd.

Use HEAD~$n instead.
