dired-move-to-filename-regexp does not match small files with BSD 'ls -lh'

[Richard Lewis]

On FreeBSD, ls -lh marks the size of small files with a B:

$ ls -lh README
-rw-r--r--  1 richard  maths   538B Jan 17  2001 README

but dired does not recognise this as a valid file size.

[I'm using GNU Emacs 22.0.50.2 (i386-unknown-freebsd5.4, X toolkit, Xaw3d scroll
bars) of 2005-04-06]
