GNU now provides .lz with new packages but they also provide the .gz
to support older systems. Lzip appears to have advantages where only
poor and/or slow connections are available. Thus there would also be
a size advantage in distributing the test data as a separate archive
in all the formats desired. A case could be made for also providing
.zip archives for those who deal only with .Net and java on Windows
(one of those is now MS for UWP and Store apps).

+1 junk the test data used by few, over the comments enjoyed by many!
Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
