I agree that just running mergemaster CAREFULLY does the job. The only
time I was ever burned was when I was in a BIG hurry and ended up
wasting a LOT of time. (I think I also learned.) Of course, I also
remember merging /etc before we had mergemaster.

I am a bit curious why you recommend against -U, though. I've been
using it since it was added and have never had a problems. It's saved
me quite a bit of time. Is thee a corner case that I'm missing?
