I don't see why it's tricky to do portably.  If the RHS contains '&',
escape it with a backslash.  That's simple and portable, no?

The advantage of using & as a delimiter is that any other choice of a
delimiter means one more character to escape (namely, the delimiter).

(Admittedly these are all minor points.)
