changectx: issue a FilteredRepoLookupError when applicable We capture FilteredxxxError and issue a FilteredRepoLookupError instead with a sightly different messsge. The message will likely get more improvement in the future. error: filtered revision '4'

repoview: add a FilteredRepoLookupError This exception is a more precise RepoLookupError that will allow us to issue a special message when we end up accessing a filtered revision.

repoview: add a FilteredLookupError class This exception is a more precise LookupError that will allow us to issue a special message when we end up accessing a filtered revision.

repoview: add a FilteredIndexError class This exception is a more precise IndexError that will allow us to issue a special message when we end up accessing a filtered revision.
