changectx: ancestor should only prefer merge.preferancestor if it is a revision
The value '*' do currently designate that bid merge should be used. The best
way to test bid merge is to set preferancestor=* in the configuration file ...
but then it would abort with unknown revision '*' when other code paths ended
up in changectx.ancestor .
Instead, just skip and ignore the value '*' when looking for a preferred
ancestor.
