Hmm, good point!  I'm not sure why I added the reverse mode of
`string__append_list' in the first place.  In any case, doing so was
clearly a mistake.  I think it is quite safe to remove this mode
without worrying about backwards compatibility, since as Simon says
any code which uses it is probably wrong.
