[PATCH v5 19/26] switch: add short option for --detach

[Nguyễn Thái Ngọc Duy]

"git checkout" automatically detaches branches and --detach is not
that useful (--no-detach is more likely). But for "switch", you
may want to use it more often once you're used to detached HEAD. This
of course adds -d to git-checkout but it does not harm (yet?) to do it.
