-I is a bad idea....

man tar
....
     -I include-file         Opens include-file containing a list
                             of  files,  one per line, and treats
                             it  as   if   each   file   appeared
                             separately  on  the command line. Be
                             careful of  trailing  white  spaces.
                             Also beware of leading white spaces,
                             since, for each line in the included
                             file,  the  entire  line (apart from
                             the newline) will be used  to  match
                             against  the initial string of files
                             to  include.   In  the  case   where
                             excluded   files   (see  X  function
                             modifier) are also  specified,  they
                             take  precedence  over  all included
                             files. If a  file  is  specified  in
                             both   the   exclude-file   and  the
                             include-file  (or  on  the   command
                             line), it will be excluded.


And BTW: how should your patch work as long as "7za" does not behave like all 
other standard compressors and will not work as expected in a pipe?
