Diff algorithm

Anyone implement a diff algorithm in xTalk?

My goal is to compare the words in two blocks of text and output a combined
block of text showing words present in the first block but absent in the
second ("deleted") in red with a strikeout, and words present in the second
but absent from the first ("added") in blue.

This is one of those things that seems simple enough, yet in looking at the
various algorithms floating around the Web apparently it is not.  I had a
version that kinda worked on lines but only kinda, so here I am....
