You have a HEAD which points to some actual commit, but no index or
working tree. I don't think there is a particular name for this state.

You can get something similar in an existing repo by deleting all of the
working tree files and removing .git/index.

By itself, I don't think so. But you can use "git checkout -f" to
discard changes in the index and working tree, setting them back to the
state in HEAD.

At one point, some people used "git checkout" as a no-op, because it
would print the "ahead/behind" information with respect to the upstream.
These days, that information is part of "git status", so I suspect
people use that instead.
