title: NetBeans git merge failed. It say I have local modify and 'review' show nothing
body: <p>I fetch the branch and merge it in the unchanged branch, but I couldn't merge it with my branch. It say I have local modified in local working directory, then I click 'review' and it show nothing (It mean no modified files, right?)</p>
  
  <p>I have try git diff local branch with remote branch and it show no file too.
  I also try to fetch + rebase this branch and it say the same as git merge say.</p>
  
  <p>What wrong?</p>
