When I was maintaining GDB (many years ago), touching *anything* in
the state machine that figured out what to do next when the inferior
stopped was guaranteed to produce several bugs for every fix.

In the changes we made, I tried to reduce that tendency, and make
the code more modular and less fragile.  Today, "just" adding a new
flag for this may be as simple as you hope.
