Re: Problem with new display in buffer-menu command

[Richard Stallman <rms@gnu.org>]

    Instead of having one default display width for the Buffer column,
    support having a default range (or small set) of widths to pick from.
    When the need to truncate (with the current default width) is first
    determined, change the current default width to a larger one (in the
    default range or from the default set of widths) which is capable of
    displaying the full file name.  Then simply re-call the logic to
    re-generate the display with the new current default width.

Something like this might work.  It could try various means of omitting
part of the names -- from the end, from the middle, whatever -- and pick
the first one that makes them all unique.

I don't think this is a must-fix, but if someone wants to work on it,
we could install it.  Probably after the release.
