  • Revision ID: v.ladeuil+lp@free.fr-20090507114803-sxykmkuzrkdj2pr3
Fix bug #373157 by properly setting the default values.

* tests/test_annotate_config.py:
(TestConfig.test_create_initial_config): Urgh, remove pdb breakpoint.

* annotate/config.py:
(gannotate_configspec): Deleted, can't be used for default values
and not used for validation: useless.
(gannotate_config_filename): Turned into a function so that tests
get proper isolated result (evaluating the path at load time
forbids the test framework overriding).
(GAnnotateConfig.__init__): Add default values *only* if the
'window' section doesn't exist. Assigning them unconditionally
defeats the config file purpose... Also delete the 'spans' section
since nobody use it.
(GAnnotateConfig.apply): Coerce config values when we use them.
(Gannotateconfig._save_custom_spans): Deleted (dead code).
