ilammy 8329ee9fd6 Do not lose carry bit in addition edge case 
Previous code was losing the carry bit in 'all ones' case, when adata[i]
= bdata[i] = SEXP_UINT_T_MAX, and carry = 1 too. In this case expression
(SEXP_UINT_T_MAX - bdata[i] - carry) overflows and yields an incorrect
value SEXP_UINT_T_MAX which results into carry being incorrectly set to
0 after addition.

We need to avoid the second overflow when calculating the new value of
the carry bit. One way to do this is at first check for the overflow in
(adata[i] + bdata[i]), and then throw in the (previous) carry bit.

I have also given "n" more expressive name and added a comment about
the reason why we need that temporary variable.
