Extract the duplicated code into test_no_missing_in_packs() and use that instead. Refactor the resulting extraction so that if any git commands fail, their return codes are not silently lost. We were using sed to filter lines. Although not incorrect, this is exactly what grep is built for. Replace this invocation of sed with grep so that we use the correct tool for the job. Instead of verifying each file of `alt_objects/pack/*.idx` individually in a for-loop, batch them together into one verification step. The original testing construct was O(n^2): it used a grep in a loop to test whether any objects were missing in the packfile. Rewrite this to sort the files then use `comm -23` so that finding missing lines from the original file is done more efficiently. While we're at it, add a space to `commit_and_pack ()` for style.
