This is mostly intentional, see bug #958. The purpose of this change is
to avoid the loss of a computation that you interrupted to look at its
progress. For example if you stop the computation to change the debug level
and make an error, you should still be allowed to continue the computation.
This include spurious ^C stroke.

Honestly, I did not know that ^C would get you out of the breakloop, and it is
not documented. I suggest to use ^D instead.

Right, except that ^D is tricky - click it twice in a row by accident and you lose your 3 week-old session with 6000 lines of input and output.  It'd be nice to be able to unbind ^D at the regular prompt, but because it's not a readline binding, it's not immediately obvious to me whether it's doable or not without mocking with shell and terminal settings.  I'll switch to the 3rd option then - 3 ^Js in a row, which is much safer.
 

Cheers,
