 -d::
        After packing, if the newly created packs make some
        existing packs redundant, remove the redundant packs.
+       Also runs gitlink:git-prune-packed[1].
 
 -l::
         Pass the `--local` option to `git pack-objects`, see
         gitlink:git-pack-objects[1].
 
+-f::
+        Pass the `--no-reuse-delta` option to `git pack-objects`, see

         Do not update the server information with

+--window=[N], --depth=[N]::
+       These two options affects how the objects contained in the pack are
+       stored using delta compression. The objects are first internally
+       sorted by type, size and optionally names and compared against the
+       other objects within `--window` to see if using delta compression saves
+       space. `--depth` limits the maximum delta depth; making it too deep
+       affects the performance on the unpacker side, because delta data needs
+       to be applied that many times to get to the necessary object.
