WTF no comments

So, I'm reading some source code from Plan 9, and I just realized that it's nearly uncommented. I expected a little more from Rob Pike.

what:

i++; /* increment i by 1 */
p[i] = 0; /* set p[i] to zero */

why:

/* set that to zero because the `FOO' protocol requires exactly
   `N' characters */
i++;
p[i] = 0;

I hope you see the difference.
