 \brief Tests the command line interface, \c xmlpatterns, for the XQuery code.

 This test is not intended for testing the engine, but all the gluing the
 command line interface do: error reporting, query output, variable bindings, exit
 codes, and so on.

 In other words, if you have an engine bug; don't add it here because it won't be
 tested properly. Instead add it to the test suite.
