    // to retain the line numbers. KTextEditor changes are required to make this work correctly

    // breakpoint marks and their moving cursors can be removed, and the breakpoints can be marked
    // as inactive/detached. The breakpoints will remain inactive until the user activates them
    // again, e.g. by double-clicking an inactive breakpoint's row in the Breakpoints tool view
    // (such a breakpoint reactivation is not yet implemented, only planned).
