A pushable button similar to the one you can find for customizable
options.  That would be reasonable I think.  Juri, what do you think?

It's one of the basic problems of the customization interface that many
people hate it and so we don't get many suggestions how to improve it.

'maximum should be possible without greater problems.

'current-window-width is a wishlist item: We could reserve float values
between 0 and 1 for specifying an appropriate fraction of the window
width for the width of name+size fields.  The program would have to
recalculate the new actual width (in `window-configuration-change-hook')
every time the size of the Buffer Menu window changes.

We could also show the full name of the current entry in a tooltip (when
the mouse is over it) and/or in the echo area.

And finally we could split a window like the Buffer Menu's one into as
many subwindows as there are fields and allow the use to drag vertical
dividers between the various fields in order to reveal hidden
information.  Currently such an approach would work iff all fields used
the same font size.
