Bug Description
Description: Ubuntu 11.04
Release: 11.04
Architecture: x86_64
package version: 5.0.0-2
It always returns 0 instead of 1.
Simple way to check:
cp /etc/hosts /etc/hostname /tmp/
cd /tmp
diff -q host* ; echo $?
xz host*
xzdiff -q host* ; echo $?
I could not create a simple test case for 2 (this would be a case where diff fails due to an error while xzdiff can run correctly, i.e. unreadable xz files do not qualify).
xzcmp behaves the same way, as they are the same program

Simple (but probably not very elegant) fix for xzdiff/xzcmp
Now it passes the above test.
