passphrase-fd $msg & $pass from command line?

[Hack Hawk]

Now I feel stupid.  The moment I give up, I find my answer.  Seems to 
always work this way.  Thanks to Paul Evad (May 2000) from the archives, 
slightly altered.  I must've typo'd the first time I tried this because now 
it's working.  :)

$command="echo '$passphrase\n$msg' | gpg --clearsign --passphrase-fd 0"
