I wouldn't say that we are (well, at least me) way ahead. I'm just
throwing ideas out nyself, except that I was hazarding a syntax.
Someone else was in the process of RFCing line disciplines, so I pretty
much just backed off. Particularly because what I know is limited
to what I've read, so I'm mainly just wagging this as I go along.

Okay, standard.

This would be akin to my :col. (Lay all the lines out, and hack off
all the columns past $MAXLEN.)

This would be akin to my :block. (When put on top of, er, under, er,
whichever way, the :text discipline to stop at new lines.)
