The Python C API documentation has this information--if a function is
documented as borrowing a reference, then it behaves as you were
expecting (it doesn't increase the reference count).  If it's
documented as creating a new reference, it does increase the reference
count.

I don't know if there's a simple rule to know of a function borrows or
creates a new reference; I've never noticed one.
