changed it so it includes the original Subject in parens. This

breaks RFC822 and Sendmails all over the world will probably
automatically add an empty Subject: header)
The Subject: header field has always been optional according to the rfcs.
Older versions of sendmail added an empty one if it was missing, but
newer ones do so no longer.
You can either move the extraction of the Subject: to it's own recipe,
or do something like this:
MATCH # unset match
:0c
* ! $ ^X-Loop: $\LOGNAME
* 1^0 ^Subject:\/.*
* 1^0
| ( formail -rt -I "Subject: Autoreply${MATCH:+ (was: $MATCH)}" \
