[Doug Goldstein]

Add support for the field width to be specified as an argument by using
the '*' modifier. See the POSIX.1 specification for more details on
conformance at
http://pubs.opengroup.org/onlinepubs/9699919799/functions/printf.html

This change make the following calls equivalent:

printf("%6s\n", "test");
printf("%*s\n", 6, "test");
