Perhaps the "where possible" caveat needs to include a test whether
IO::Pty is installed? It's evidently not there by default everywhere.
It's possible that we should just move the goalposts and say IO::Pty
is required for TAP testing. I can foresee that we'll have to do
that if we ever want automated tests of psql's tab completion,
for example.
