Procmail, itself, doesn't do that.  You have to pipe the messge through
a 'filter' that makes the changee.  e.g.:

  :0 fhw
  * ^X-Amavis-Alert:BAD HEADER,
  | sed -e "/^Subject: /& {{added text}} /I"

  :0 A
  $MAILDIR/Maildir/.Spam/

This will change 
   "Subject: Some Text" 
to
   "Subject: {{added text}} Some Text"

Yes, procmail _does_ understand regex patterns that have whitespace in 
them _most_ of the time.  Trailing whitespace characters ares tripped,
So if you want a space as the *last* thing in a pattern, you have to use
something like "some text[ ]" instead of "some text ".
