Fix off by one handling MOD directive optional arguments Fixes an off by one in handling the optional arguments to the MOD directive as of changeset 928c033c0cd0. Thanks to Alex Evans <varmfskii@gmail.com> for reporting the problem and a suggested fix. This fix is different but should be more stable should the rest of the parsing code be refactored in the future.
