pub fn clear_breakpoint_handler()Expand description
Forget any installed handler, so every later :bp is a no-op.
The crash debugger’s path needs this: a fault hands the terminal to the
debugger, and restart (§9.7) re-runs the program from inside that screen
— a stop handler firing there would take the terminal from the debugger
already holding it. Disarming before the hand-off is what keeps the two
surfaces from fighting over it.
