AH, yes that clears things up!

One annoying thing about my view is that we'd also have to change the
touch matcher too.  On the other hand, maybe it would pay off in the
long run.  If I'm using a matcher to pull patches and I think my first
instinct is to think that it means *my* foo and not their foo.
Likewise, when I say 'conflicted', I mean 'conflicted for me'.  So the
problem with intuition is that not everybody has the same one.  If I'm
right about this, I kinda want to hold out for something that does match
intuition better.

But if it really is just pretty arbitrary then we should definitely go
with what's easiest (as you say).  Also supporting your view: in the
worst case, we could always start with the easiest to implement and then
change our minds later.

As you can see I can pretty much flip/flop to any position on this.

I think some people might like a mechanism for forcing pull to fail 
if there are conflicts.  But I'd be happier to hear opinion from
non darcs hackers.
