Doc Text:	Previously, the xzgrep command returned exit status 1 when contents of one or more files did not match the requested pattern. With this update, xzgrep returns exit status 0 if there is at least one match of the pattern, which makes the xzgrep behavior consistent with the default grep command behavior.	Story Points:	---

Description Tomas Dolezal 2014-06-11 12:42:29 UTC

Description of problem:
If xzgrep founds match in only portion of tested files, it returns exitcode 1 where EC 0 is expected as it is default behaviour for grep.

Version-Release number of selected component (if applicable):
xz-4.999.9-0.4.beta.20091007git.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. echo test | tee test1 | tee test3; echo text > test2
2. xz -z test*
3. xzgrep -l test *.xz || echo fail

Actual results:
test1.xz:test
test3.xz:test
fail

Expected results:
test1.xz:test
test3.xz:test


Additional info:
-l is optional for reproducing
