Yes, manually edit this file, but FIRST MAKE A BACK UP.  :-)

I think, but may be wrong, regenworld will pick up anything and everything in 
emerge.log and add it to your world file.  Definitely create a back up of /
var/lib/portage/world if you do not have one already, because you can diff it 
later on to see how much weight it has put on.
