No a feature!  I answered the original poster by mail a week or two
ago (whenever it was posted).  After that the poster reposted to
net.unix-wizards saying there was no response from net.unix.
Suggestion -- wait a week or more for your article or propagate
through the net and another week to get something back before you
repost.

Rm checks to see if there is a controlling tty.  In the case of a
shell execing a background process, the child does not inherit the
controlling terminal.  Rm checks to see and if no controlling terminal
it acts as if you said "-f".  This is why no error message in this
case.
