Treating spaces and newlines alike could be a good idea since
filling converts between them.

What is the "actually available height"?  I am not sure what
that phrase means.  However, the use of the current font for
either spaces or newlines seems to be a mistake, because of
the case I mentioned earlier (more than one line of small text
in a paragraph of larger text).
