I can't reproduce the problem using the latest zgrep 1.7-pre1:

$ echo 'foo bar' > foobar
$ echo 'foo baz' > foobaz
$ zgrep -q foo * ; echo $?
0
$ zgrep -q bar * ; echo $?
0
$ zgrep -q baz * ; echo $?
0
$ lzip -v *
  foobar:  0.182:1, 550.00% ratio, -450.00% saved, 8 in, 44 out.
  foobaz:  0.182:1, 550.00% ratio, -450.00% saved, 8 in, 44 out.
$ zgrep -q foo * ; echo $?
0
$ zgrep -q bar * ; echo $?
0
$ zgrep -q baz * ; echo $?
0

What is the exact configuration that failed? (Command line used, 
versions of grep and decompressors, compressed formats, file 
permissions, etc).


Best regards,
Antonio.
