When doing a comment, should
@username-san notify the user that they've been replied to?
@AndrewGrimm-san'd me, and I didn't get notified of it.
The rules for this are quite complicated. In particular to this case see rules 3 and 9.
From 3: In most (all?) cases including
-san will mean that the name is not matched and the user is not notified.
From 9: If the comment was edited to include your name in certain circumstances you might not be notified.
