verbose flag causes spurious test failures

[Tres Seaver]

The tests run fine on the trunk without any '-v' flag::

  $ svn co $ZSVN/zope.testing/trunk zope.testing
  $ cd zope.testing
  $ /opt/Python-2.6.5/bin/python bootstrap.py
  ...
  $ bin/buildout
  ...
  $ bin/test --all

but one fails when run with '-v'::

This needs to be fixed in zope.testrunner, not zope.testing.

[Marius Gedminas (mgedmin)]

I cannot reproduce this, most likely because zope.testing.doctest (and its tests) are long gone.
