In style(9) the example
	for (p = buf; *p != '\0'; ++p)
		;	/* nothing */
is given, but I really like the explicit continue; enough so that I'm
wondering if the example in style(9) should be changed to
	for (p = buf; *p != '\0'; ++p)
		continue;
to encourage people to write that way (I hope I'm not the only person
who simply never thought of adding the explicit continue?).

Realizing that questions of style tend to provoke huge debates: Please
send me your opinions off-list, and I'll only make this change if the
emails I get are at least 75% in favour.
