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".

# Note: These tests depend on the hard-coded value of 5 as the maximum depth
# we will follow recursion. We start the depth at 0 and count links, not
# repositories. This means that in a chain like:
#
# A --> B --> C --> D --> E --> F --> G --> H
# 0 1 2 3 4 5 6
#
# we are OK at "G", but break at "H", even though "H" is actually the 8th
# repository, not the 6th, which you might expect. Counting the links allows
# N+1 repositories, and counting from 0 to 5 inclusive allows 6 links.
#
# Note also that we must use "--bare -l" to make the link to H. The "-l"
# ensures we do not do a connectivity check, and the "--bare" makes sure
# we do not try to checkout the result (which needs objects), either of
# which would cause the clone to fail.
