This path just adds the "--keep" option to keep original files unchanged.
Could you please explain why that option would be helpful?
It's not clear, from the patch.
It allows, for example, format conversion preserving file date without
using an additional "touch":
$ lzip -kd autoconf-archive-2013.02.02.tar.lz
$ gzip autoconf-archive-2013.02.02.tar
2013-02-05 17:56 autoconf-archive-2013.02.02.tar.gz
2013-02-05 17:56 autoconf-archive-2013.02.02.tar.lz
$ gzip -cd autoconf-archive-2013.02.02.tar.gz >
autoconf-archive-2013.02.02.tar
$ lzip autoconf-archive-2013.02.02.tar
2013-02-05 17:56 autoconf-archive-2013.02.02.tar.gz
2013-02-09 23:00 autoconf-archive-2013.02.02.tar.lz
