Comment (by cremona):
I agree that the more general function David suggests is useful, and it is
also very easy to write: set D=I+J, write 1=x+y with x in I/D, y in J/D
using the function here, then for any d in D we have d=(dx)+(dy) with the
factors in I,J.
On the other hand implementing this directly using the method we already
use would perhaps be more efficient. So let's not hold this up for that.
On the docstring comment -- yes, and the same is true for very many
patches in there now!
