Message 111407 - Python tracker

Part of the patch has already been independently implemented (support for custom `dict_type`s). As for the custom delimiters the patch is somewhat incomplete. Let's take for instance delimiting by space characters (e.g. `delimiters = (" ", )`). ConfigParser would input <space><delim><space> so it would be quite bizarre.

Brett, I have a patch ready but it depends on issue7113 changes I've made.
