doctest bug with nested triple quotes

[Michele Simionato]

This is my file
$ python -c "print open('x.py').read().encode('base64')"
IiIiCj4+PiBkdW1teSA9ICcnJwpzb21ldGhpbmcKaGVyZQonJycKIiIiCmltcG9ydCBkb2N0ZXN0
OyBkb2N0ZXN0LnRlc3Rtb2QoKQo=

but anyway I think Peter Otten is right, the problem is with the
missing dots.
It makes sense, actually, but for some reason I would never have
thought
of it (I did not expect doctest to be so smart to strip the dots even
inside a string).
Thanks for the feeback and the quick solution,
