For some reason the Python API manual is silent about PyList_Append
incrementing the reference count.  But I did check, and you are correct,
the reference count is incremented when added to a list.

This is fine, thanks for doing this.  I cannot give you check-in
permission as I am not a maintainer.  Please wait until one of the
maintainers signs-off before you go ahead.

Cheers,

Phil
