rebase --abort Unespected behavior

Hello,

I don't know if this is a bug but it was unexpected for us. I accidentally added untracked files through a `git add .` while doing an interactive rebase and aborting the rebase deleted those files. Is this to be expected?

To reproduce: mkdir test_folder cd test_folder git init touch first git add . git commit -m 'First' echo 1 >> first git add . git commit -m 'Second' echo 2 >> first git add . touch second git commit -m 'Third' git rebase -i HEAD~2 #set second to be edited git add . git status #second should have staged git rebase --abort ls #second has been deleted

Not sure this is an expected behavior. Thanks Blaise Garant
