Yes.  That procedure would only make sense for one-dimensional arrays
anyway.  It could just as well throw an error when passed a
multi-dimensional array, no?

I think I agree, but I’d like to hear what Andy thinks, since he’s done
a major overhaul of this part recently (and actually, thanks to this,
generalized-vectors.c is very small.)
