1,065 comment lines become 340; the code is unchanged. Corrected: - CMSG_CANCEL_CAST carried CMSG_CANCEL_AURA's doc; - the inspect reply is parsed, then dropped; - mount failures reach the player as error lines, so they are no longer a deviation; - the pet-stable note moves from SMSG_INVALIDATE_PLAYER to the stable constants.
