* A test helper to exercise the progress display.
*
* Reads instructions from standard input, one instruction per line:
*
* "start <total>[ <title>]" - Call start_progress(title, total),
* Uses the default title of "Working hard"
* if the " <title>" is omitted.
* "progress <items>" - Call display_progress() with the given item count
* as parameter.
* "throughput <bytes> <millis> - Call display_throughput() with the given
* byte count as parameter. The 'millis'
* specify the time elapsed since the
* start_progress() call.
* "update" - Set the 'progress_update' flag.
* "stop" - Call stop_progress().
*
* See 't0500-progress-display.sh' for examples.
