Subject: mprintf: Fix processing of width and prec args

Prior to this change a width arg could be erroneously output, and also
width and precision args could not be used together without crashing.

"%0*d%s", 2, 9, "foo"

Before: "092"
After: "09foo"

"%*.*s", 5, 2, "foo"

Before: crash
After: "   fo"

Test 557 is updated to verify this and more
