I've been going through this lately also (mainly due to forgetting -1  
on updates) and put together  a script, which I can post later if  
anyone wants.  However, the bottom line for me is to do "emerge -pc  
package" for each package in world to see what (if anything) else  
pulled it in.  If it was pulled in by something else, I remove it from  
the world file, unless I explicitly want it installed.    The script  
just does most of that, producing a file that makes it easier for me to  
see what -pc would remove and what is actually installed.

Currently my world file is 292 lines, with 1863 packages installed  
(from "eix-installed -a".)

I'm not going to even try regenworld, as I'm in the midst of converting  
to the 17.1 profile, and have quite a number of packages that don't yet  
seem to cope with that change well.
