I was talking about things that do have newlines in them.  :-)

If you have the following text, where some of it underscores.  Like
this:

      This is a text with words This is a text with words This is a text with words 
                                                    -------------------------

Then you fill it with `M-q':

      This is a text with words This is a text with words This is a text
                                                    --------------------
      with words
----------


and then you get this ugly-looking result.

I have no idea how to fix this in an except in an extremely hacky way,
though.
