pullreport: issue a message about "extinct" pulled changesets Changeset pulled from a remote repository while already obsolete locally can end up hidden after the pull. Hiding obsolete changesets is a good behavior but silently "skipping" some of the pulled content can get confusing. We now detect this situation and emit a message about it. The message is simple and the wording could be improved, however, we focus on the detection here. Evolution is still an experimental feature, so the output is open to changes. In particular, we could point out at the latest successors of the obsolete changesets, however, it can get tricky is there are many of them. So we delay these improvements to another adventure. Another easy improvement would be to merge this message with the previous line about the new nodes and their phases. This is a good example of cases where we can only transmit a limited amount of data to users by default. We need some sort of "transaction journal" we could point the user to.
