Cool. That's just great.
If I had known it's suffcient to put ideas on a web page to have
people put them into code I would have started doing this much
earlier :-)

I think this covers only the hush shell version. We need something
like this instead:
#ifdef CFG_HUSH_PARSER
rcode = parse_string_outer(p, FLAG_PARSE_SEMICOLON |
FLAG_EXIT_FROM_LOOP);
#else
rcode =run_command (p, 0);
#endif
