Ticket #659: command_repeater.sh

#! /bin/sh
# This script repeats its arguments until failure.  stderr/out of the failed/terminating run is stored in ${OUTNAME}.log which can be set as an argument to -o. `time` for each run is logged in ${OUTNAME}_times.log.   For convenient testing uncomment THRESH and associated test.
