Fix new "useless_vec" warning from clippy +nightly 

Explanation at
https://rust-lang.github.io/rust-clippy/master/index.html#/useless_vec

This is the non-tests subset of the same-named commmit in !1388,
(recreated by hand by me, and then checked against that commit;
I stole the commit message from Nick's.)

This should be uncontroversial I think.
