Hi Timothy,

Thank you very much for all the testing you have done on lzip. :-)

You can look at the output of -lv. If the dictionary size is smaller 
than the uncompressed size, then the file can be compressed more. (All 
my files are already compressed at level -9):

$ lzip -lv *.lz
   dict   memb  trail    uncompressed      compressed   saved  name
