Ahem. Your solution is actually better than mine, since it operates on
properly tokenized data whereas mine is regexp'ing text
more... "heuristically". As Jamie Zawinski wisely said,

  Some programmers when faced with a problem think, "I know, I'll use
  a regular expression." Now they have two problems.

I will switch over to your way in the next Distel version :-)
