File: refill.el.html

Provides a mode where paragraphs are refilled after changes in them
(using after-change-functions). This gives something akin to typical
word processor-style filling. We restrict refilling due to self-insertion to the characters which trigger auto-fill.

It partly satisfies a todo item in enriched.el for some value of without slowing down editing too much. It doesn't attempt to do anything (using window-size-change-functions?) about resizing windows -- who cares?

This implementation is probably fragile and missing some special cases -- not extensively tested. Yanking paragraph breaks, for instance, won't DTRT by refilling all the relevant paragraphs.

You could do it a bit more efficiently (and robustly?) with just an auto-fill function, but that doesn't cope with changes other than through self-insertion. (Using auto-fill and after-change
functions together didn't seem winning.) This could probably
benefit from a less-general and faster fill-paragraph-function, ideally as a primitive.

The work is done in a local post-command hook but only if refill-doit has been set by the after-change function. Using post-command-hook ensures simply that refilling only happens once per command.

[Per Abrahamsen's maniac.el does a similar thing, but operates from
post-command-hook. I don't understand the statement in it that after-change-functions don't work for this purpose; perhaps there was some Emacs bug at the time. ISTR maniac has problems with whitespace at the end of paragraphs.]
