   3 Subject: xz: Check if the file already has custom suffix when compressing.

   6 xz: Check if the file already has custom suffix when compressing.
   7
   8 Now "xz -S .test foo.test" refuses to compress the
   9 file because it already has the suffix .test. The man
  10 page had it documented this way already.
