The previous behavior of the -A option was to retain any previously packed objects which had become unreferenced, and place them into the newly created pack file. Since git-gc, when run automatically with the --auto option, calls repack with the -A option, this had the effect of retaining unreferenced packed objects indefinitely. To avoid this scenario, the user was required to run git-gc with the little known --prune option or to manually run repack with the -a option. This patch changes the behavior of the -A option so that unreferenced objects that exist in any pack file being replaced, will be unpacked into the repository. The unreferenced loose objects can then be garbage collected by git-gc (i.e. git-prune) based on the gc.pruneExpire setting. Also add new tests for checking whether unreferenced objects which were previously packed are properly left in the repository unpacked after repacking.
