Hi,

I'm having problems trying to merge one branch into another.

$ git --version
git version 1.4.1

$ git branch
* master
   origin
   rf-al7230b
   softmac-experimental

$ git checkout softmac-experimental

$ git diff

$ git pull . master

Now, I think I've seen this once or twice before, and I think I solved 
it by checking out all those files listed by "git diff" one by one.

However, when I try this now, the list produced by "git diff" shrinks 
and grows as I check more of them out, and I can't seem to get it down 
to 0 again.

I have also tried the -f flags for checkout and pull, no difference.

What's going on?

Thanks,
Daniel
