I had to remove STRICT to allow NULL to be passed for the seed. When I
first modified test_bitmapset.c to only choose a random seed when it
received NULL, I thought it was strange that the function appeared to
return NULL. It took me a minute to realise I was getting the STRICT
NULL short-circuiting.
