title: How do I tell Git it got moves/renames wrong (false positives)
body: <p>I'm merging two branches in git, having a week worth of work each and some of the files were moved or renamed and modified.</p>
  
  <p>Git seems to get the stuff completely wrong in some cases and it says file a was moved to file b when in reality they are totally unrelated.</p>
  
  <p>I'm having quite a few such false positives (roughly 25%). I would like to influence the algorithm Git uses to figure out whether a file was moved, renamed or is new.</p>
  
  <ul>
  <li>I'd like to assign higher priority to names. (file a was moved from folder foo to folder b) yet git insists that it was renamed to be file b in folder foo - totally unrelated)</li>
  <li>I'd like to bump up the similarity index above which Git considers a file to be rename/move</li>
  </ul>
  
  <p>I know I read somewhere I can do the latter and I hope I can do the former too, but my googling skills are failing me today.</p>
