wget -m imply -np?

I wonder if it would make sense for wget -m (--mirror) to imply -np
(--no-parent).  I know that I, at least, have no interest in ever
mirroring anything "above" the target url(s) -- generally, that leads to
the whole Internet.  An option to explicitly include the parents could
be added.

Just a suggestion.  Thanks for the great software.
