That'd be better, yes. I never do anything tweaking with TERM anyway,
so I don't know the options/effects.
jladage suggested to do the workaround in buildout, btw: add the

This doesn't work, surprisingly. It *is* a corner case.
It are tests where z3c.testsetup tests that it runs tests correctly.
That's a lot of "tests" in one sentence, which means that the test
output comes from separate python processes that run tests. So if I
import readline in z3c.testsetup's tests, I still get the output from
the test runners that are being tested.
Sigh, difficult to explain, such a recusive testing thingy :-)

And you'd do this per-project and not in core zope.testing, right?
Fine. Uli already send me some example code, so I'll do that (and put
the code snippet on my weblog so that google can find it).

Can we safely assume that a specific set of control characters needs
to be escaped? It sounds a bit dangerous to me.
