Further improvements to "pipework".ex19p

Version advanced to 0.99.18ex19p.

Fixed occasional failure to immediately display prompt after
previous command output was abandonned by ^C, particularly with
"--more--".

Completely removed the "~" temporary prompt, and simplified some
logic.

Added indication of pthread running to "show version".
