Include commit message in wiki page edit Slack notifications
Currently, in at least up to 10.3.6, Slack notifications for wiki page edits do not include the commit message. This is pretty much the most interesting thing a notification for a wiki page edit would have (in addition to perhaps link to a diff what changed, but I suppose that's not doable at the moment).
So, please change Slack wiki edit notifications to include the commit message. (And similarly also for other wiki change notifications, unless they're already included in them, haven't checked.)
