- This is a possible argument. The trouble is, there's no end to it. I mean,
- the algorithms to split lines in wordprocessors come from elementary texts -
- I don't know what, maybe from Knuth's code for TeX, or something earlier.
- But there's not much more to a wordprocessor than packaging up a bunch of
- such routines, then selling it (as an extreme case).
