 Replying to [comment:1 TomH]:

 his edit list.

 Wouldn't that be the definition of "broken" for this functionality? I
 mean, the counter shows one thing, the list another without any
 explanation... Closing as "invalid" does not seem like the best solution
 to this - IMHO at the very least this issue should be kept on file for
 reference since it *is* a bug.

 Speaking of a solution for this - I guess some code would be needed around
 edits counter cache (if we are to stick with this implementation), e.g.

 with-conditions

 But that seems to issue additional select on every update - not sure if
 this is feasible (although if there is a btree index on user_id in the
 changesets table then it should be pretty quick?).
