I've added some additional filters I needed to 'hg missing'. Thought they might be useful enough to include in your version.
Tests are not included because I haven't figured out how to modify existing tests to add mine in test_contains.py without messing everything up yet. In addition they currently don't pass for me at the moment :( I'd be glad to write some, would appreciate some pointers :)
thanks, I'll happily accept your changes.
About the tests, I just found out that somethings wrong there (test_graft fails for me, but I don't use hg graft a lot ...). I know that the tests are quite a mess, but don't have time to rewrite them (at least not in the foreseeable future).
