    index: add a dirty bit reflecting unsaved changes Teach the index when it is "dirty", and has unsaved changes. Consider the index dirty whenever a caller has added or removed an entry from the main index, REUC or NAME section, including when the index is completely cleared. Similarly, consider the index _not_ dirty immediately after it is written, or when it is read from the on-disk index. This allows us to ensure that unsaved changes are not lost when we automatically refresh the index.
