I'm talking about qtests:

    qmp_discard_response("{'execute':'change', 'arguments':{"
                         " 'device':'floppy0', 'target': %s, 'arg': 'raw' }}",

versus

    qmp_discard_response("{\"execute\":\"change\", \"arguments\":{"
                         " \"device\":\"floppy0\", \"target\": %s, \"arg\": 
\"raw\" }}",

See above.  Notice how the %s becomes a JSON string, with automatic
backslash escaping.
