t5613: clarify "too deep" recursion tests
These tests are just trying to show that we allow recursion
up to a certain depth, but not past it. But the counting is
a bit non-intuitive, and rather than test at the edge of the
breakage, we test "OK" cases in the middle of the chain.
Let's explain what's going on, and explicitly test the
switch between "OK" and "too deep".
