#1 Rummy - Bad check for ace high

[Bill Godfrey]

rum.c/hand_win (legacy-rummy/rum.c v1.1)

Ace high check begin with
if (low_face == 0)

Given an ACE_HIGH run, low_face will have a value of
ACE (1).

Additionally, it appears that the loop which checks for
an ace high run will always fail, since ACE has a value
lower than (ACE_HIGH-size)
