Hmm. I would think test-dump-cache-tree would do it. I don't know why
read-tree wouldn't fill it in, though.
Interestingly, on my git.git repo, I had an empty cache. Running "git
read-tree HEAD" filled it (according to test-dump-cache-tree). It seems
that running "git checkout" empties the cache. So perhaps git could do
better about keeping the cache valid over time.
