Alex Riesen (raa.lkml@gmail.com) recently observed that git branch would fail with no error message due to unexpected situations with regards to refs. For example, if .git/refs/heads/gu is a file but "git branch -b refs/heads/gu/fixa HEAD" was invoked by the user it would fail silently due to refs/heads/gu being a file and not a directory. This change adds a test for trying to create a ref within a directory that is actually currently a file, and adds error printing within the ref locking routine should the resolve operation fail. The error printing code probably belongs at this level of the library as other failures within the ref locking, writing and logging code are also currently at this level of the code.
