Merge if statement

[S-H-GAMELINKS]

set_namespace_path_i has these code.
But, using same returtn value.

    if (!rb_is_const_id(id)) {
        return ID_TABLE_CONTINUE;
    }
    if (!rb_namespace_p(value)) {
        return ID_TABLE_CONTINUE;
    }

I think better to merge if statement.

    if (!rb_is_const_id(id) || !rb_namespace_p(value)) {
        return ID_TABLE_CONTINUE;
    }

This looks good to me. The only logical reason that this would be done is if perhaps each block had a preceeding comment explaining the meaning of that particular condition. Or possibly before it was a more complex condition that was simplified.
