I've encountered some problems with the patch.  One is that it breaks
the display of all face attributes in the customize-face buffer.  I've
determined the part of the patch that triggers this, though I haven't
yet figured out just why this bit of code breaks the display.  Also, it
appears that the widget-unselected face does not completely replace
widget-inactive where it's intended to do so, but I need to do more
testing and debugging here to find out why.  Until I've fixed these
issues the patch is not suitable for installing, so I'm also holding off
with the accompanying documentation.  (But in preparation for the
documentation I looked more closely at the Widget manual and found
several typos and other issues, for which I opened bug#70502.)
