Question: Does it need sphinx 1.8.3+ or is it fine to also use with sphinx 1.7.x?

I don't see why it would need Sphinx 1.8.3. The only change relevant to #26451 (the new sphinx) was to replace SageNB's sphinxify to just use sage.misc.sphinxify. So SageNB should remain compatible with whatever the Sage library is using, rather than having code duplication (and code divergence) between the two.

In any case, I'm building and running doctests now.

it works with version 1.7.6 sphinx too.

All tests pass for me with sphinx 1.7.6 and sphinx 1.8.3. The legacy notebook appears to work, and docstrings look nice, so I think the sphinxify function is working properly.

Is there anything else that I should test? Other changes from the sagenb side of things?
