Fix a (relatively harmless) braino. I confused myself over the for() loop
that counted the number of elements in argv. The counter is incremented
in the next-iteration section of the loop, not the body, so at termination
it's already "counted" the element that failed the continuation test - in
this case the NULL argv terminator.
