[PATCH 0/4] Reactions to v2.37.0-rc0 test coverage report

These patches add test coverage or simplify code based on discoveries in the
test coverage report (specifically, some that I highlighted at [1]).

 1. Add tests for 'git update-index --verbose'.
 2. Add 'git gc --cruft' without '--prune=now' to test.
 3. Drop an always-NULL parameter from an internal method.
 4. Revert 080ab56a4 (cache-tree: implement cache_tree_find_path(),
    2022-05-23).

Any subset of these could be taken (or dropped), but I thought they would be
worth considering.

Thanks, -Stolee
