Ok, ok, just go ahead and shoot me now....I deserve it.  My only possible
excuse is that after working on a sparc system over a 9600 bps serial line
from a 21.6 bps modem connection (and routed through 3 ssh connections) has
made my mind about as sluggish as the response from the computer I am
working on.

That said, thanks....basically what I wanted to confirm (no *real* way to
do it, but a sort-of way to do it in procmail).  That tip looks to be
precisely what I wanted (in spite of my garbled groo-quality-slow-of-mind
request).
