this is one thing that byron understood in his version of rc.
he had
	x=``ifs {cmd}
the `` was required since `singleton was allowed in his version.
i think that one could just extend the grammar to allow
	x=`ifs {cmd}
and i think it would be even better if it were
	x=`splitchars {cmd}
so ifs is never set.
