rcfiles cascade - wow!

Hi all,

Did I mention I was impressed by MHonArc? I just
checked to see if rcfiles would cascade, i.e.

mhonarc -rcfile a -rcfile b mbox

It appears to work just like cacading stylesheets; i.e rcfile a is
used, except where augmented or overridden by rcfile b. I am totally,
totally impressed. Wow. Sorry for cluttering the list with praise, but
that just knocked my socks off.
