Add $process.run() and $process.run_regex() functions
$process.run(<prog>[ <args>...])
Return trimmed stdout.
$process.run_regex(<prog>[ <args>...], <pat> [, <fmt>])
Return stdout lines matched and optionally processed with regex.
Each line of stdout (including the customary trailing blank) is matched (as a
whole) against <pat> and, if successful, returned, optionally processed with
<fmt>, as an element of a list.
