But, dear Antoine, i don't know *any* editor that is capable to 
handle the following code correctly:

#ifdef __APPLE__
    if (!PyArg_ParseTupleAndKeywords(args, kwdict, "iiO&O&|OOi:sendfile",
        keywords, &out, &in, _parse_off_t, &offset, _parse_off_t, &sbytes,
#else
    if (!PyArg_ParseTupleAndKeywords(args, kwdict, "iiO&n|OOi:sendfile",
        keywords, &out, &in, _parse_off_t, &offset, &len,
#endif
                &headers, &trailers, &flags))
