Add options for program (-p) and to turn off waiting (-w) which is now

on by default.

The default is to wait after each counter is tested.  Since the prompt
would go to stdout you won't see it if you're redirecting the output
of the executed sub-program to /dev/null, so just press return to
continue or Ctrl-D to stop.
