repoview: wrap changelog class when filtering The class doesn't yet do anything. I'll move the filter-aware overrides from the changelog class over one by one to this class in coming patches. That will leave the changelog class simpler and will centralize more of the filtering logic to repoview. I could not measure any performance difference.

3a6ddacb7198 clfilter: add actual repo filtering mechanism Pierre-Yves David <pierre-yves.david@ens-lyon.org> parents: diff changeset	255 Unlike attributes, this object intercepts all method calls. This means that
3a6ddacb7198 clfilter: add actual repo filtering mechanism Pierre-Yves David <pierre-yves.david@ens-lyon.org> parents: diff changeset	256 all methods are run on the `repoview` object with the filtered `changelog`
