Not to my mind.  doctest is intentionally picky about exact matches, for
reasons explained earlier.  If the docs for a thing say "integer division or
modulo by zero" is expected, but running it says something else, the docs
are wrong and doctest's primary *purpose* is to point that out loudly.

I could change the exception example to something where Python didn't
gratuitously change what it prints, though <wink>.  OK, I'll do that.
