Add missing tests for showing a tree with "git show". Let's test for
showing a tree, two trees, and that doing so doesn't recurse.
The only tests for this code added in 5d7eeee2ac6 (git-show: grok
blobs, trees and tags, too, 2006-12-14) were the tests in
t7701-repack-unpack-unreachable.sh added in ccc1297226b (repack:
modify behavior of -A option to leave unreferenced objects unpacked,
2008-05-09).
Let's add this common mode of operation to the "show" tests
themselves. It's more obvious, and the tests in
t7701-repack-unpack-unreachable.sh happily parse if we start buggily
emitting trees recursively.
