Michael Haggerty 5387c0d883 commit_ref(): if there is an empty dir in the way, delete it ... Part of the bug revealed in the last commit is that resolve_ref_unsafe() incorrectly returns EISDIR if it finds a directory in the place where it is looking for a loose reference, even if the corresponding packed reference exists. lock_ref_sha1_basic() notices the bogus EISDIR, and use it as an indication that it should call remove_empty_directories() and call resolve_ref_unsafe() again. But resolve_ref_unsafe() shouldn't report EISDIR in this case. If we would simply make that change, then remove_empty_directories() wouldn't get called anymore, and the empty directory would get in the way when commit_ref() calls commit_lock_file() to rename the lockfile into place. So instead of relying on lock_ref_sha1_basic() to delete empty directories, teach commit_ref(), just before calling commit_lock_file(), to check whether a directory is in the way, and if so, try to delete it.
