Re: fill-paragraph-or-region

[Richard Stallman]

    It seems like a bad idea to me: fill-paragraph is already complex enough:
    what's the benefit of conflating the two?

The benefit is to keep `fill-paragraph' as the name of the command
that M-q runs.  That name is better even though it now has the feature
of doing something different for certain interactive calls.

The complexity added to `fill-paragraph' is a handful of lines.
Not significant.
