Does a documentation exist how "doctest" manipulates "set_trace"
and what it expects that the manipulation succeeds.

Apparently, "doctest" has replaced my "set_trace" in "zpdb"
by its non working implementation of "set_trace".

I can understand that my "set_trace" would not have worked
(as probably "sys.stdout/err" points somewhere else then usual),
but I have difficulties to understand why "doctest"'s "set_trace"
does not work (at all).
