bug#68892: 'tr' function | Outputs printed before the command prompts

[Ricky Tigg]

OS: Fedora v86_64. coreutils v.: 9.3. Shell: bash v. 5.2.26.

Hello. Normally outputs are printed after the command prompt; "#" "$" on my
system.

(...)@(...):~$ rpm -ql coreutils | head -2
/usr/bin/[
/usr/bin/arch

Unexpectedly, through a pipe invoking 'tr', outputs are printed before the
command prompts.

(...)@(...):~$ rpm -ql coreutils | head -2 | tr '\n' ' '
/usr/bin/[ /usr/bin/arch (...)@(...):~$

Regards.
