C coding style

Something I've adopted that I think is useful is using a
continue statement when you have an empty for or while
statement. For example

	for (cp = buf; *cp != NULL; cp++)
		continue;

or

	while (*cp++ != NULL)
		continue;

It has the same effect of just an empty statement but
there is something there for your eyes to grab ahold of.

I first saw this used in some of the kernel code in 4bsd;
I assume it was Bill Joy's idea.
