seq: solve e13188e7ef7bbd609c1586332a335b4194b881aa more cleanly

* src/seq.c (print_numbers): Don't switch c_strtold -> strtold
in order to accommodate the locale-dependent behavior of our internal
asprintf use.  Instead, simply set the locale to C before calling
asprintf, and then set it back afterwards.
