As we already walk the history of the branch that gets merged to come up with a short log, let's label it with names of the primary authors, so that the user who summarizes the merge can easily give credit to them in the log message. Also infer the names of "lieutents" to help integrators at higher level of the food-chain to give credit to them, by counting: * The committer of the 'tip' commit that is merged * The committer of merge commits that are merged Often the first one gives the owner of the history being pulled, but his last pull from his sublieutenants may have been a fast-forward, in which case the first one would not be. The latter rule will count the integrator of the history, so together it might be a reasonable heuristics. There are two special cases: - The "author" credit is omitted when the series is written solely by the same author who is making the merge. The name can be seen on the "Author" line of the "git log" output to view the log message anyway. - The "lieutenant" credit is omitted when there is only one key committer in the merged branch and it is the committer who is making the merge. Typically this applies to the case where the developer merges his own branch. Signed-off-by: Junio C Hamano <gitster@pobox.com>
