As a quick
git grep -E '%[ +0#-]*#[ +0#-]*(\*|[0-9]+)?(\.(\*|[0-9]+)?)?p'
shows, nobody uses the # flag with %p. Moreover, I think users are
unlikely to show up since gcc will complain with
warning: `#' flag used with ‘%p’ gnu_printf format [-Wformat]
Since default_width is effectively always 2*sizeof(void*), we can
simplify the prologue of pointer() and save a few instructions.
