The updated documentation was easeier to follow (even though I had a
"Huh?" moment with "Opportunistically" a bit).  Comparing with the
previous version (with my rebase to get rid of the dependence on the
other topic) and this one, I see a few more code paths have learned
to pass "struct repository *" pointers throughout the callchain,
which is very nice.

Will replace.  Thanks.
