[PATCH 0/3] Handle negatives in bigint arithmetic

["S. Gilles" <sgilles@xxxxxxxxxxxx>]

Finally, I can actually propose a fix instead of just complaining.
As usual, take if you like and scrap if you don't. I'll be content
as long as (-1) + 1 = 0.

S. Gilles (3):
  Convert bigint tests to use testr
  Allow bigparse to handle negative numbers
  Handle (-1) + (1) and (-3) - (-2) with bigints
