This can probably be a forward declaration.

Done.

I don't think you should point to bugs unless it's an open issue. If someone
care, they will look at git blame to find out the bug associated to the change.

+1, we should not point to bugs.

[whywhat, 2015/03/10 13:00:44]

I believe there should be at least some pointer on where this event comes from.
The bug would be easier to update than the code.
