They're all the same mechanism. For instance,

define sillybt
backtrace
backtrace
end

If q should stop backtrace, IMO it should stop sillybt too.

But it won't work. C-c is implemented as the exact same thing as
typing q at a pagination prompt: eventually a quit exception is
thrown. So you will only stop the currently printing backtrace and
things will keep on going.
