You may want to update the big comment block about all cases at the
beginning of this function.

has_dash_dash is calculated as (argc > 1) && !strcmp(argv[1], "--"),
so when argc == 1, the has_dash_dash must be zero, the "&&
!has_dash_dash" is redundant. But it makes me wonder what we do with
"git checkout abc def -- xyz". I think both old and new code do not
see "--" as a separator like it should (and should also error about
multiple refs given). Maybe something worth fixing too while you're
updating this code.
