+--no-reuse-object::
+       This flag tells the command not to reuse existing object data at all,
+       including non deltified object, forcing recompression of everything.
+       This implies --no-reuse-delta. Useful only in the obscure case where
+       wholesale enforcement of a different compression level on the

+
+--compression=[N]::
+       Specifies compression level for newly-compressed data in the
+       generated pack.  If not specified,  pack compression level is
+       determined first by pack.compression,  then by core.compression,
+       and defaults to -1,  the zlib default,  if neither is set.
+       Data copied from loose objects will be recompressed
+       if core.legacyheaders was true when they were created or if
+       the loose compression level (see core.loosecompression and
+       core.compression) is now a different value than the pack
+       compression level.  Add --no-reuse-object if you want to force
+       a uniform compression level on all data no matter the source.
