Close from commit: c380f1a6ff11d50be725279950c1a8a16b0f851f by Claes Nästén
Started the work, introduced a CommitSet for grouping and observing commits being pushed while at it. More testing required before this can be moved to this site.
It would be nice if the keywords were case-insensitive and please mark the new comment on the task in a way that makes it clear that it stems from commit #XYZ.
