To comply with C99 and POSIX standards, snprintf should return the number of bytes that would be written to the string (excluding the terminating NULL byte) if the buffer size was big enough. Before this change, the return value was the minimum of the standard return and the length of the buffer. Rarely is the return value of grub_snprintf or grub_vsnprintf used with current code, and the few places where it is used do not need to be changed.
