My initial reaction too (and surely it is not a bug that functions
behave inconsistently in regions where they are not documented to work
at all), but on the other hand, noninteger m,n do appear to give a
well-defined distribution, and perhaps there's a way of making sense
of it? I wouldn't think it corresponds to noncentral hypergeometric
