(nonstandard %n and '+' with %x), and ones not found by -Wformat on 386's (some db_expr_t's are still printed as ints). I decided not to change the arg type for %n from [unsigned] int to register_t, since about half of the uses of %n are to print plain ints and casting to [unsigned] long for %n is no harder than for %x.
