pretty.c: add %x00 format specifier.

Browse Source 
This adds a %xXX format which inserts two hexdigits after %x as a byte
value in the resulting string.  This can be used to add a NUL byte or any
other byte that can make machine parsing easier.  It is also necessary to
use fwrite to print out the data since printf will terminate if you feed
it a NUL.
