Revert r38879, 38880 "(bug 14002) Change cascade protection warning message to be consistent with cascade-protection 'blocked' message."
Incompatible change to message, and just seems kind of ugly. It's usually easier to maintain the core message without having to remember to slap "and the bit that always follows it" on the end every time.
Probably the other message referred to should be fixed to follow general conventions, rather than this one changed to break them. :)
