[Rd] bug in fisher test---p-value cannot be Inf (PR#4688)

[kjetil at entelnet.bo]

I just found a bug in fisher.test(). This is rw1080, on windows XP.

A p-value can certainly not be Inf, but:

> religion
           Costumbres rel orig
Religion      Si Algunas veces Nunca
  católica  2121          4700  6234
  prot/evan  100           216  2461
  otra C      27            67   502
  otra         0             0    14
> fisher.test(religion, workspace=2000000)

        Fisher's Exact Test for Count Data

data:  religion 
p-value = Inf
alternative hypothesis: two.sided
