How can use Tortoise to go back to the previous revision and make it the HEAD without a working copy?
- I checked-out the HEAD revision to create a local copy;
- Exported the previous revision to another folder using the Repository Browser;
- Copied those exported files into my checked-out folder, overwriting existing;
- Re-added all files in my checked-out folder;
- Committed my checked-out folder.
That seemed to work.
