------------------
- ``setup.make_renamer()``: generated ``rename`` function improved:
existing positional options default to ``None``; instead of ``uid``,
``o`` (object) or ``brain`` can be specified (by name).
- ``setup.make_query_extractor()``, generated ``extract_query`` function improved:
don't convert a ``Language`` string to a list if it's value is ``all``
- ``zcmlgen`` module:
- Bugfix for changes detection
- If changes are found but disallowed (non-development setup),
and if ``sys.stdout`` is connected to a terminal,
start the debugger
