I do not think we are choosing any option in the codepath at
all.

What I mean by the normal "checkout" is what checkout_entry in
entry.c does.  There is no other option than (1) above.  I would
want to see an extremely good justification if you need to touch
that codepath to implement this fringe use case.

I do not think there is nothing that writes file contents to
stdout/pager other than "git cat-file" or "git show"; I do not
think they are what you have in mind when talking about managing
the files under /etc.  So unfortunately I do not understand the
rest of the discussion you made in your message.
