When inserting newlines AUCTeX often uses the function
`comment-indent-new-line' which checks `comment-auto-fill-only-comments'
(among other things) to determine if it should actually insert a
newline.  And if the variable is t then it does nothing.

To me this looks like a bug in Emacs.  At least with respect to
documentation.  The doc string of the function gives no hint that the
function should only be used by auto-fill.  But the fact that it checks
`comment-auto-fill-only-comments' seems to suggest that.  And if this is
really the case, then the function cannot be used by other parts of
Emacs or packages like AUCTeX.
