This seems like an interesting extension of rm(1) in a fairly harmless manner.
It seems like a fairly logical extension of the tcsh rmstar variable.  The
one concern I would have with it is that unlike the rmstar variable, it would
always run even if the rm command is run in a script.

What do you think of adding a flag to enable this behavior so users
could make rm an alias that uses the flag?  That would keep it from
effecting scripts.
