Killed bug in processing of 'h' prefix. Patch taken from linux-2.1.129.
Implemented snprintf and similar functions. It took a lot of thinking,but the modifications were relatively simple and straightforward.
Oops, forgot '%m'...
Added local version of sprintf (bsprintf and bvsprintf) offering few newformat strings:
%I IP address %#I IP address in hexadecimal %1I IP address padded to full length %m strerror(errno)
