/* NAME
/*	msg_stats_print
/* SUMMARY
/*	write MSG_STATS structure to stream
/* SYNOPSIS
/*	#include <msg_stats.h>
/*
/*	int	msg_stats_print(print_fn, stream, flags, ptr)
/*	ATTR_PRINT_MASTER_FN print_fn;

/* DESCRIPTION
/*	msg_stats_print() writes an MSG_STATS structure to the named
/*	stream using the specified attribute print routine.
/*	msg_stats_print() is meant to be passed as a call-back to
/*	attr_print(), thusly:
/*
/*	... SEND_ATTR_FUNC(msg_stats_print, (void *) stats), ...
