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

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