Comment (by tscrim):
For filtered algebras, we (only) have F,,0,, <= F,,1,, <= ..., so for
graded modules, we'd have G,,i,, = F,,i,, - F,,i-1,, because we want that
construction of F,,i,, = F,,i-1,, (+) G,,i,, (starting with F,,0,, =
G,,0,,). Actually, there is something that is wrong; the setminus isn't
correct because it removes 0. It should be a quotient F,,i,, / F,,i-1,,,
but other than that, it's consistent.
