Excellent! I've updated the patch so that it uses that dictionary. I also
added the ability to pass a locals dictionary to _sage_, which complements
and/or overrides the symbol_table['mathematica'] dictionary.
The documentation for this function won't be very visible, since it starts
with an underscore, so I was contemplating setting up a mathematica-
specific .sage function that accepts a locals dictionary and has a copy of
this documentation. In the end I didn't do this because I don't
understand the consequences (or why there are separate _sage_ and sage
functions at all). Opinions?

Yes, I'm not sure it's related to the patch either. For the record I get
the correct behaviour with the patch:
{{{
sage: mathematica('N[Pi, 1]')
3.1
sage: mathematica('N[Pi, 10]')

sage: mathematica('N[Pi, 11]')
