-True, this will count carriage returns and not newlines.  In fact, it

-wanted to count all characters, counting newlines as two characters (ie,
-cr/lf).  Two ways to do it:
-	if (c == '\n') chcnt +=2; else chcnt++;
-
-or for those who like the ternary operator (like me):
-
-	c == '\n' ? chcnt +=2 : chcnt++;

-John

I think I like one of the following two better:
chcnt += (c == '\n') ? 2 : 1;
chcnt += 1 + (c == '\n');

Any comments one which one of the ones we've seen is most efficient?
