Yes, just these commands in a script work also in my environment.
(That was what I meant when I wrote: "constructing a test sample
from scratch"; it didn't lead me anywhere, since it just wasn't
reproducible in a primitive context like that.)

I think it must have to do with the shell environment that in
some way affects how 'rm -i' behaves. But I have no idea how an
external (shell-environment-)condition could look like that makes
an executed program like 'rm' behave as if all '-i' confirmations
are "magically" considered as being each answered by "no" (without
me typing anything).
