Why does rename cause a file add rather than file changed?

Question

I accidentally added and committed a file with the wrong name. No problem. Tortoise has a rename command. The command deleted the original and added the new file.

Is this just a short cut for copy, delete, and add? Does this command do anything else behind the scenes?

Answer 1

apart from just being a short-cut, it also links the history to the new file so you can still see previous revisions.
