Similar timeline entries should be grouped

[webkontakt@…]

I often experience that our users perform several (3-20+) Wiki page changes in a row (which sometimes even makes sense) and never add a comment when submitting. The result is a very long list of the same entry in the timeline, e.g.:

11:24 ProjektInfo edited by jow
11:24 ProjektInfo edited by jow
11:23 ProjektInfo edited by jow
11:22 ProjektInfo edited by jow
11:22 ProjektInfo edited by jow

This makes those small changes overly prominent, and commits and ticket changes hard to find between all the wiki changes. Perhaps such events (subsequent changes, same user, no comment) can be grouped to:

11:24 ProjektInfo edited by jow (5 recent changes)

This will make it much more readable. I don't know how it affects the RSS feeds, though.
