doc nit for sign()

The sign(X) function returns -1, 0, or +1 if the argument X is a numeric value that is negative, zero, or positive, respectively. If the argument to sign(X) is NULL or is a string or blob that cannot be losslessly converted into a number, then sign(X) return NULL.
I think it should be "returns" NULL.

Thanks for the nit report. This has been fixed (redundantly.)
