$history is not an array, it's a hash whose keys are the history event
numbers.  So (( $#history < HISTSIZE )) is always true but (( HISTNO >
HISTSIZE )) is possible.  The largest possible defined index into
$history is $HISTNO, but of course that's only valid inside ZLE.

If you're manipulating history in an "fc -p" scope or the like there's
really only $(( ${${(k)history[@]}[1]} + 1)) to get the equivalent,
which does seem like an oversight.
