Oh, nice. I'll be using that, for sure :)

Not quite; after any that do duplicate elimination (via `formail -D' or
something else).

The /dev/fd0 is pointing lynx at its own standard input, because (at
least some) lynxes have no `-'-a-like syntax to do that. (For
portability's sake, it should really be `/dev/stdin', which is a symlink
to `/dev/fd/0' (and /dev/fd is itself a symlink to /proc/self/fd...) )
