My bad.  Emacs 20.3's `buffer-string' doesn't take a BUFFER
parameter.

Er.  How weird.  `buffer-string' is an alias for `buffer-substring' in
XEmacs 21.2.  Has it always been that way?  And jere I just convinced
RMS to let `buffer-string' take an optional BUFFER parameter in Emacs
20.4, all for naught, it seems...

To clarify: In Emacs 20.4, `buffer-substring' takes mandatory START
and END params, while `buffer-string' takes an optional BUFFER param.
In XEmacs 21.2, there's only one function, which takes three optional
params -- start, end, and buffer.  I think the Emacs 20.4 thing makes
more sense.
