Forget about my earlier, wide off target post about this. Can't cancel e-mail,
sorry...

Well, of course this one wins the prize. This rang a bell (a cathedral-sized
one). Not sure about the "documented" bit, however. But the recommended bash
trick for detecting a non-interactive shell is '[ -z "$PS1" ]'!! It does leave
one suspicious...

Redhat even distributes an /etc/bashrc containing the following pearl:
"...
# For some unknown reason bash refuses to inherit
# PS1 in some circumstances that I can't figure out.
# Putting PS1 here ensures that it gets loaded every time.
PS1="[\u_at_\h \W]\\$ "
..."

Argh.

Sorry about that.
Cumprimentos,
