:I tried this again and got much better results for two-or-more element
:arrays, but singleton arrays were still getting subscripted as scalars.
:Investigation led me to this fragment of paramsubst():
:
: if (isarr > 0 && !plan9 && (!aval || !aval[0])) {
: val = dupstring("");
: isarr = 0;
: } else if (isarr && aval && aval[0] && !aval[1]) {
: val = aval[0];
: isarr = 0;
: }

:Well, look at that. If we have a singleton array, make it into a scalar.
:This doesn't have anything to do with multsub() at all!

:Does anybody remember why this code is here? What part of the world is
:going to come crashing down if that "else if" clause gets deleted?
It's a pf artifact. Looking in 2.00.03 sees it there in a slightly
different incantation but logically the same.
