Message 246697 - Python tracker
Have also been confronted to this bug (imo) and this happen from time to time to me : I often like to ends my (big) functions defs and calls (those that span over multiple lines thus..) with that extra comma, so that when/if I add another argument (on a new line) later then there will be only a + line in my VCS). There seems to have a consensus to apply the patch (unless it's not finished?).. regards,
