Pure light checkout?

[Jari Aalto]

Would it be possible to add a checkout option that does nothing else
but

- retrieves only the HEAD of all files of a branch
- Records the repository location from where the checkout was done

It would not be possible to do anyhing else but viewing the contents
of that "pure Checkout" directory or asking to "pull" and overwrite
all the files (no merge, just straight overwrite).

USE CASE
========

                Repo
               / \
          Devel   Host

At "Devel" you develop the software. You push to "Repo" when you
consider "Devel" is stable. At "Host", you do no development
whatsoever, no changes, nothing, else my deploy the files.

Cases applicaple:

- Publishing web pages
- Publishing documentation
- Viewing latest source files
- Doing a packaging work of upstream snapshot
