factor documentation problem

[Varga Dániel]

$ factor 3628746859628453216852492
factor: `3628746859628453216852492' is not a valid positive integer
Try `factor --help' for more information.

------------------

I firmly believe that `3628746859628453216852492' is a valid positive
integer. :)

"factor --help" did not help at all.

"info factor" very implicitly contained the information that the input must
be less than 2^64. I guess this should be made more explicit. It did not
contain any hint whether or not this 2^64 limit depends on the architecture.
