Hello,
I'm just wondering that bash (reproduced with 5.2-rc1 under Debian 11) seems to
determine LINES and COLUMNS from stderr.
It uses stderr because if the shell is interactive, stderr is guaranteed to
be a terminal, and that's the file descriptor it uses to perform job
control. When it's not interactive, all bets are off, and stderr is usually
a safe default. There's no consistent approach across shells.
