bug#5054: 23.1.50; buffer-menu truncated fields

A> It also wouldn't be a bad idea, IMO, to change the default binding of `C-x 
C-b'
A> from `list-buffers' to `buffer-menu'. (I do that in my .emacs.)
It seems the two commands produce the same window currently, except
list-buffers gives some tips message at startup.

A> FWIW, the code from buff-menu+.el could be integrated.

Too many 'other leading brands' of C-x C-b... good thing I'm using the
official supported version, else you guys would never know there was bugs:-)
