Hello! I'm running into issues with grep in -z mode. I've managed to minimize it into this:
$ seq 2 | grep --null-data --quiet '[12].2' ; echo $?
0
$ seq 2 | grep --null-data --quiet '[1-2].2' ; echo $?
1
I'd expect the two expressions to mean the same. I've tried this with
the latest version built from the official sources, 2.21. I've also
found [1] which might be related but it wasn't updated for almost 2
years. Or is this expected?
Thanks!
