Yet it's not very clear from the error message:

    fatal: git checkout: updating paths is incompatible with switching branches.
    Did you intend to checkout 'origin/abcde' which can not be
resolved as commit?

I wonder if we should reject -t as a value of -[Bb] by adding new parseopt flag to reject values starting with '-'. In this case, branch names can't start with '-'. There may be cases where we accept option value starting with '-', but I suspect the other way is dominant.
