Single line status updates with minimal update sequences.
Project description
Latest release 20200229: Upd: can now be used as a context manager, clearing the line on exit. Upd.without is now a context manager, returning the older state, and accepting an optional inner state (default ""). Upd is now a singleton factory, obsoleting upd_for. Upd.nl: use "insert line above" mode if supported.
