Michael Haggerty 446397774a files_transaction_commit(): clean up empty directories ... When deleting/pruning references, remove any directories that are made empty by the deletion of loose references or of reflogs. Otherwise such empty directories can survive forever and accumulate over time. (Even 'pack-refs', which is smart enough to remove the parent directories of loose references that it prunes, leaves directories that were already empty.) And now that files_transaction_commit() takes care of deleting the parent directories of loose references that it prunes, we don't have to do that in prune_ref() anymore. This change would be unwise if the *creation* of these directories could race with our deletion of them. But the earlier changes in this patch series made the creation paths robust against races, so now it is safe to tidy them up more aggressively.
