title: Files listed as pending changes when doing merges that didn't change?
body: <p>We've had this happen more than a few times were we consider it to be more than a fluke at this point. When we are merging back after we are complete with our branch there are way more changes then their should be. So most of the files showing as pending changes never changed (in most of the cases in neither the branch or the base). When i compare them (i use beyond compare) there are no differences. I haven't went through all the files that didn't change but in most cases it seems like they are marked as <code>[merge]</code> and the files that actually changed are marked as <code>[merge,edit]</code>.   </p>
  
  <p>In one case we probably changed around a 100 files it pending changes showed more than 22,000 changes. We tried checking them in at one point thinking tfs would be smart enough to know what files changed and which didn't. But it checked in all files. Does anyone know whats going on and how to fix it?</p>
  
  <p>We are running TFS 2012 w\ Update1<br>
  Everyone is using Visual Studio 2012 w\ Update 1.</p>
