If there is a failure to lock a reference that is likely caused by a D/F conflict (e.g., trying to lock "refs/foo/bar" when reference "refs/foo" already exists), invoke verify_refname_available() to try to generate a more helpful error message. That function might not detect an error. For example, some non-reference file might be blocking the deletion of an otherwise-empty directory tree, or there might be a race with another process that just deleted the offending reference. In such cases, generate the strerror-based error message like before. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu>
