outgoing: fix possible filtering crash in outgoing (
issue3814)
If there is no outgoiing changesets but we have filtered revision in outgoing.excluded
We run into a filtering related crash. The excluded revision should not be there
in the first place but discovery need cleanup in default, not stable.
To run the tests, do:
cd tests/
python run-tests.py
See http://mercurial.selenic.com/wiki/WritingTests for
more information on writing tests.
