Subject: [PATCH] checkout_branch: support "-" argument

git natively supports `-` as an argument to `git switch` and `git
checkout`. It is shorthand for `@{-1}`, which is a way to refer to the
last branch you were on.

forgit used to interpret `-` as a branch name, detect that it does not
exist yet and create a new one with this name, which does not work.

Add a check whether `-` is passed on the command line and do not create
a new branch in this case
