T16901: Email notification mistakes log action for new page creation was closed because we're now in a much better situation and on the right path, but there's more to do:

This patch solves the problem to a certain level, which handles: create,
delete, move, restore, change. change is the default"
If the only problem with the patch is that i doesn't resolve the problem
completely, then I quote Nikerabbit "Let's try to get this in and then improve
further as needed".
For this or any future patch: any log action has a name to show on Special:Log
which is also translatable (unless there is still some very ugly deprecated
method to log), so an easy fallback for the unhandled cases would be to notify
something like "An action of type $log_action has been performed on the page"
A proper and complete fix would require the notification system in core and other core features or extensions to communicate in some way, but that will be another bug.
