If a string-based configuation entry had whitespace in it, it would be
reassembled via a round-trip through the python interpreter, resulting
in a line like this:
PidFile /home/dkimpy-milter/pid file
produces a string like "['/home/dkimpy-milter/pid', 'file']", which is
clearly wrong.
I don't want to encourage people to use paths or other strings with
whitespace in them, but if we're going to fail on them we should be
failing explicitly, not doing a weird transformation that will just
break.
This is concretely useful for the DNSOverride mechanism, which is
where i ran into the problem when trying to set up testing that could
work without setting up an emulated DNS system.
