Turns out that "v += e" currently generates an error ("requires two
arithmetic or two string operands"), so it seems safe to me to introduce
it as append-to-vector concurrent with deprecating "v + e" (which from the
discussion on the list it seems likely current has little or no use).

BTW, "v1 += v2" likewise generates an error, even when "v1 + v2" works.
