Filling is one thing, but paragraphs are another.  texinfo-mode relies
on the paragraph definition being...  eccentric... to avoid filling
lines that start with "@word ".

I think the paragraph definition should be more traditional, and
`fill-paragraph-function' should be adjusted to do the right thing on
the @directives that we don't want to have filled.
