Thanks so much!
I altered it slightly because fill-paragraph was always doing full
justification. Then I figured I'd pass the justify parameter along to
fill-region, as well.
So, here's the body of the function I'm using, in case some one else
wants to use it (or, more likely, I mis-place the code and need it
again):
| (interactive "P")
| (let ((point (point))
| (mark (and mark-active (mark))))
| (message (format "justify is %s" justify))
| (if (and mark (not (equal point mark)))
| (if justify
| (fill-region (min point mark) (max point mark) 'full)
| (fill-region (min point mark) (max point mark)))
| (if justify
| (fill-paragraph 'full)
| (fill-paragraph nil)))))
