+-A::
+       Same as `-a`, but any unreachable objects in a previous
+       pack become loose, unpacked objects, instead of being
+       left in the old pack.  Unreachable objects are never
+       intentionally added to a pack, even when repacking.
+       When used with '-d', this option
+       prevents unreachable objects from being immediately
+       deleted by way of being left in the old pack and then
+       removed.  Instead, the loose unreachable objects
+       will be pruned according to normal expiry rules
+       with the next linkgit:git-gc[1].
+
 -d::
        After packing, if the newly created packs make some
        existing packs redundant, remove the redundant packs.
