I might not want to implement <br> this way, since display-box:
contents involves a bit of complexity that I wouldn't want to impose
on such a common element.  Then again, we could perhaps special-case
<br> inside the implementation of display-box: contents.  But it's
not just a trivial matter of removing the existing <br>
implementation and replacing it with the above.
