index: test dirty index bit Test that any changes to the index will mark the index as dirty. Also ensure that when we initialize a new index, read the index contents from disk, or write the index contents to disk that we reset the dirty flag to zero. Further ensure that an unforced read with dirty contents (when the on-disk index has not changed) does _not_ reset the dirty flag as we have not updated the contents of our index and our unsaved contents remain intact.
