title: How to detect renames in Tortoise HG Workbench
body: <p>I had a significant number of files in my project just on the root level so I decided to clean them up by placing them into folders for Manager classes, API classes etc. When I go into Tortoise HG's workbench, I see that is thinks I have removed all of these files and added them (with the folder extensions). I see on the "add" items there is an option to detect name changes so I click it but it doesn't seem to be able to find anything (even when dropping the similarity to 0)</p>
  
  <p>How can I "find" these files to avoid an ugly commit?</p>
