Is HEAD in git case insensitive on all platforms?

Question

Using msysgit on Windows, I can do this:

git checkout head

or

git checkout HEAD

Either works. I don\'t ha

Answering to cover Mac OSX (Mavericks):

$ git checkout HEAD
Your branch is up-to-date with 'origin/master'.

but:

$ git checkout head
Note: checking out 'head'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b new_branch_name

HEAD is now at f44b740... fix if endScreen(s) not present

By the way, that hash is the head of the current branch (in my test, the same has contained in .git/refs/heads/master)

Interesting behaviour.
