That's true.  The logic is still there; there's an XMLResultsStream
(spelling might be wrong) class that will write out the results as
XML.  We didn't have time before 2.0 to wire up the command-line
options to pick amongst output streams.

There was a very good reason for changing to the pickled representation;
it's much, much faster.  With test databases with thousands of results,
the XML results file could take minutes to load; in the pickled form it
takes seconds.

We'd like to have the option to choose between them, but there's little
bit of thinking to do about how exactly that should work.  Presumably
something like:

  --output-stream=xml_results_stream.XMLResultsStream -o foo

or the like.
