Subject: [PATCH] Cloning from a repo without "current branch"

If the remote repository does not have a "current branch", git-clone
was confused and did not set up the resulting new repository
correctly.  It did not reset HEAD from the default 'master', and did
not write the SHA1 to the master branch.
