We're talking about the with-syntax-table macro here?  The code in
xemacs cvs and emacs-21.4a are strictly identical and include the
copy.  The docstring also says that you work on a copy ("... set to a
copy of TABLE.").  Did emacs-cvs change that?  It's a change that does
make a lot of sense.

I guess I can't checkout emacs-cvs until savannah works again,

As for the bug with with-syntax-table/backwards-sexp, I've started
looking at it.  It's interestingly hairy code.
