Shouldn't trust me that much ;-)

It could be a problem if some grammar somewhere will have a node type 
called "not_comment", and the regexp will still match it. Or 
"pseudo_string", etc.

Not sure how realistic that scenario is, up to you. The authors of such 
major modes could opt for a stricted regexp individually, too.

Still not ideal: it says "refill all the lines within a defun", but the 
refilling step only touches the paragraph around point.

Also about NEWS: "textual element" is a little value; it really refills 
a single paragraph. That distinction is meaningful when a string or a 
comment are long, containing several paragraphs inside.
