repoview: pin revisions for `local` and `other` when a merge is active I've hit this a couple of times, where pulling with a dirty `wdir` obsoletes `p1` and updating to the successor results in merge conflicts. The problem was resolving them failed immediately, complaining that the old checkout was filtered. The change in `test-rebase-obsolete.t` is because there's an outstanding merge conflict in a rebase operation. The summary prompt to merge seems incorrect for this scenario, but that's an existing issue. Differential Revision: https://phab.mercurial-scm.org/D8980
