Thank you for this. I saw that that was a way to do it, but putting it
in my .emacs conflicts with running emacs -Q. But assuming that it's
OK at this point to run emacs without -Q, I did try it.

There is no difference in the result: whether I restrict emacs to xfont,
ftfont, or ftcrhb, it still loads the "Bold" file even when I select the
"Book" version from menu-set-font.

Where does this leave us? It does still seem like a bug (albeit one that
apparently affects very few people).
