Thanks for the link. I had forgotten that discussion, but re-reading
it brought most of it back. Given how the discussion ended -- with
valid use being that --cc-cmd names a program which accepts a single
argument -- then the above patch to recipients_cmd() might indeed be
desirable.
And, the documentation is still lacking, saying nothing about that
single argument passed to the cc-cmd...
