I just tried to use this and realized it hadn't been pushed yet.

This series LGTM except one minor nit below and the fact that it
introduces a lot of tab-indented code in sections of test-lib.sh that
appear to be space-indented.  Given that test-lib.sh is already a mess
of indentation styles, I don't know if we care, but it would be nice if
its entropy were at least non-increasing.
