What if the terminal itself turns off BREAK processing during paste?

I'd rather not go down the xterm route... they've implemented a full
character filtering facility in there. Which I guess is ok, since this
will handle pastes for applications without any bracketing support.. but
I find it to be tacked-on fix.

Putty also eats it by the way. If that's the case for all terminals, I
would just enabled it by default.

I'm ambivalent to that. Replacing the selection seems pretty sound to me.
