#643 (May 28, 2018, 1:50:00 AM)

1. prefer existing operation; (detail / hgweb)
2. retain isolated blob nodes (amending deb2fcbda16e): avoid failure of Session.handle_change with "Missing blob", when opening theory with load command later; (detail / hgweb)
3. clarified signature -- avoid confusion with Resources.is_hidden; (detail / hgweb)
4. markup for deleted fragments of token source (NB: quoted tokens transform "\123" implicitly); (detail / hgweb)
