Editing the world and indeed world_sets file, really isn't a big deal, 
especially for deleting, as long as you delete the entire line.

Adding gets a bit more complicated, but even that isn't too bad, as long 
as you're careful to get the full package category and name correct, and 
append the :slot info if necessary.  However, while I do still hand-edit 
the (much smaller) world_sets file, I haven't hand-edited the world file 
in ages, preferring to let portage do it with emerge -C to unmerge for 
removing lines.  For adding lines, same thing, only since my emerge 
scripts add --oneshot by default (so I never have to worry about dirtying 
my world files), I do a remerge with --noreplace (and without -1) to 
actually add packages to the world file if I want them there.  That 
doesn't remerge the package due to the --noreplace, just asks me if I 
want to add the package to the world file, which I do, at that point.

Actually, my script invocation for the add is eaa <pkg>, for emerge --ask 
<add>.
