Oh God...! that'll take me a while to pull apart.  Quite the regex... and it
works... dunno why, yet. :)

hehe... I was waiting for that to come along.  :)  I just thought it looked
silly to have two seds in a row, each essentially performing a very simple
operation, and I wondered if this well-aged tool had been written to
accomplish more than one expression in one pass.  As David pointed out, that
is indeed the case.
