ftoastr: depend on snprintf, improve comments
* lib/ftoastr.c: Also mention Loitsch's draft.
* lib/ftoastr.h: Require WIDTH to be nonnegative. This isn't
needed in the current implementation, but it might simplify
speeding up the code later.
* modules/ftoastr: Depend on snprintf; this improves portability.
Suggested by Bruno Haible in the same email.
