Hi,

I am running coreutils 8.30 in AIX machine and it seems like " tail -f " is
not working as it used to be when the output is piped.

# ./tail -f test_file | grep 123

(1) root @ aixoss-automation-3: 6.1.0.0: /

It stops immediately  and it seems like this commit
https://github.com/coreutils/coreutils/commit/ce0415fda108b7ec35181118fd7a2c9ee70331ee
 has introduce this behavior.

I checked in Linux with coreutils 8.30 where it works as like earlier
versions.

Thanks
Ayappan P
