message:
Add easier access to boolean values in configuration files.
* bzrlib/tests/test_config.py:
(TestIniConfig.test_get_user_option_as_bool): Test valid and
invalid booleans values.
* bzrlib/config.py:
(Config.get_user_option_as_bool): Provide access to configuration
variables as booleans if they are defined.
(Config.__init__): I couldn't find that constructor one time too
much.
(IniBasedConfig.__init__): Ditto.
