Default generated config doesn't work

[turt2live]

The generated config has a [DEFAULT] section with all the config options but it doesn't apply the values to the config - one has to move the values to the right sections on their own.

I am just getting started using Sydent, but I think this one might be straightforward?

The comment looks to be correct, but the code gets it backwards. This is sydent.py

    # if the config file doesn't exist, prepopulate the config object
    # with the defaults, in the right section.
    #
    # otherwise, we have to put the defaults in the DEFAULT section,
    # to ensure that they don't override anyone's settings which are
    # in their config file in the default section (which is likely,
    # because sydent used to be braindead).
    use_defaults = not os.path.exists(config_file)

Dropping the not in that last line makes it work for me.

    use_defaults = os.path.exists(config_file)

Without an existing config file, it populates one that looks reasonable. Then after I add my configuration, it doesn't get overwritten on the next run.

But my config is admittedly very simple, and it's possible that I'm missing something more subtle.
