Ah, on reading the latter part of Sven's posting it seems I was
misinterpreting the "minimum value of 1" condition. I'd say the doc
leaves this ambiguous, but in practice it appears to mean that the
vector must not contain a value less than 1, rather than (as I
assumed) must contain 1 as its least value.

Given that, Sven's first example ought to work, and that's now the case in git.
