Comment (by barry.wardell):

 0001 doesn't look like it does quite the right thing. It checks that the
 two hashes (current and branch) are the same and doesn't do the checkout
 if they are.  This could be wrong in a couple of cases: if two branches
 point to the same commit, or if the repository is on a detached head which
 also happens to be pointed to by a branch.

 I think the following (untested) patch might be a better approach.
