We have to get this fixed, one way or another, because we can't have
Emacs looking this bad on a popular platform like Ubuntu.

So -- we're using the `fixed-pitch' face for keyboard stuff because the
`default' font may well use a proportional font.  (It's unusual, but
feasible.)

But in the common case, where `default' uses a fixed width font, then I
think the `fixed-pitch' face should use exactly the same font.

Is there some easy way to achieve this, by any chance?
