Excellent !
> You just have to update a bunch of doctests and review the patch!
I was ready to do that, unfortunately, that not the problem here. There seems
to be some interference with the doctest mechanism:
If you take a random test file, you'll see that the answer that is expected by
sage is printed on the screen before sage reports the error and that sage
reports that he get nothing. So it seems that the result of the patch is that
the doctest mechanism is bypassed and that the output goes directly to the
screen. I'll investigate this but I don't know anything neither about sage
output
mechanism not on sage doctest mechanism. So if anyone have a idea, please
help.
Cheers,
Florent
