(Delayed followup)

I don't quite follow set_buffer_hook. (Are hooks related to modes?)

When I'm editing with no mode, I am able to happily type way past 100
without the line wrapping, which is what I need.
(I really prefer creating my own newlines.)

But when editing *.txt files in Text mode, it reverts to wrapping.

How do I set WRAP = 1000; for Text mode, please?  (Or for all modes, if
that's easier)

I found some guidance here, but not enough:
