It does not. That's the same as doing a normal mv followed by git add. It does not record the fact that you moved it. You can verify this by moving a file and making big changes to it in the same commit. Git will forget that you moved it.
If you `git mv`, then immediately commit (without making any additional changes), I think it will recognize it as a move 100% of the time (i.e., will not use its "similarity index"). I'm not certain of that though.
Sure, but if you mv and git add without making any additional changes and then immediately commit, it'll also get picked up as a move 100% of the time.
