So I guess the oft-used M-x delete-trailing-whitespace screws up
any use of M-q?

Emacs is so dwim-intelligent about so many things that it's a
surprise to me that a period (or ! or ?, etc) meant to end a 
sentence line requires two spaces, which is fine in the middle
of a line, would still obtain at the end of a line.

Perhaps in that double-space mode the emacs user could avoid
ending a line with a period UNLESS that period was to mean
"end of sentence".

Like, he'd have to teach himself to never end a line with 
a mid-sentence abbreviation.  And he'd never get into that
mode except by deliberately invoking it, plus when he did
enter that mode a message would flash up warning him about
how NOT to end a line.

Question: do other emacs users find delete-trailing-whitespace
useful?

Crazy idea?  Maybe in that two-spaces mode, delete-trailing-whitespace
would know to NOT remove two spaces following a sentence-ender?


A problem, all this.

of entering and storing text.
