I think that sounds like a useful feature, and I'm kinda surprised that
it doesn't exist yet.  Or does it?  Anybody know?

To implement this, I guess the obvious thing would be to have a global
minor mode that'd listen to frame size changes, and then adjust the font
size up/down to reach the desired number of characters in a frame?  So
we'd have a user option font-size-adjust-target (defaulting to 80)
and a font-size-adjust-mode?
