msgs=`inc -format '%(msg)'`  &&  [ -n "$msgs" ]  &&  scan $msgs  &&  mhfixmsg 

inc and scan use the same code for their output.

No, it only returns a nonzero status if it found a problem.
I'm still not convinced; if I was going to add the header,
I'd do it whether or not mhfixmsg modified the message.  If
you want to see if it did modify it, you could run with
-verbose.  (And either filter out the "will not decode"
messages, which should go away some day, or grep for the
messages you're interested in.)
