Pulling patches of other people for examination results in conflicts

Dear all,

I am getting started with contributing to rails. The guide1 says that to examine someone else’s pull request, I should git pull their topic branch into one of my local topic branches. I do following and get a large number of conflicts.

[master]$ git checkout -b testing_patch

[testing_patch]$ git pull some_git_remote remote_topic_branch

From git://github.com/some_git_user/rails

  • branch remote_topc_branch -> FETCH_HEAD
    Auto-merging Gemfile
    CONFLICT (content): Merge conflict in Gemfile
    Auto-merging RAILS_VERSION
    CONFLICT (content): Merge conflict in RAILS_VERSION
    Auto-merging README.rdoc
    CONFLICT (content): Merge conflict in README.rdoc
    Auto-merging Rakefile
    CONFLICT (content): Merge conflict in Rakefile

How do I avoid above?
