Re: problem of released-button style mode-line

I've added a new lisp function called `fit-window-to-buffer' (which is
similar to `shrink-window-if-larger-than-buffer', but slightly
lower-level), and changed quail to use it.  Once there's some function
to check partial visibility, a hack can be added to fit-window-to-buffer
to use it.
