[Coco] Let's say you wrote a BASIC program the user is invited to change

[Juan Castro]

RENUM, as it is, does the opposite of that: it can renumber from line
X to the end, not from the beginning to line X. Yes, it does make a
lot of sense, but it'll be tricky to implement.

Guess I'll tack that on the to-do section of the README.
