I am seeing a behaviour in Git which seems very mysterious to me. I keep a clone of the Linux repository from Github to play with Git locally. To be clear, I don't do much in this repository : I fetch changes, update master, checkout a specific version, and sometimes I try out a Git GUI to see what the visualization looks like on a big project. TLDR version: I never did any changes to the files in it.

Strange behaviour

Earlier today, I checked-out master and pulled changes from Github. Everything seemed to go fine. But I suspect it actually didn't. This is what git status looks like now.

axel@macbook ~/Depots/linux $ git status
# On branch master
# Changes not staged for commit:
#   (use "git add <file>..." to update what will be committed)

#

no changes added to commit (use "git add" and/or "git commit -a")

Where do these changes come from, I wonder. Now comes the worst part. Let us see what happens if I try to get rid of those files and check them out again.
