Because the sum of the whole is greater than the parts. Most features in git
for example are developed on topic branches. This makes it possible to keep
unfinished code separate from the production branch that people actually use.

You should edit the working tree, since that's where the conflict will be
staged. When you're done, commit the results and that will be a new commit
on the branch you're on.

Both branches should most definitely not have exactly the same code. If they
did, there would be no point in merging them. The merge-result shouldn't
have the same code as any of the branches either, unless you actually want
to throw one branch away, in which case you'd be far better off doing just
that.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
