I would not call it poor-man's. It is 'without complexity' and
that is a good thing, especially when you are not doing any
submodule stuff.

I think the above list "for x" is correct, but probably the code
wants to comment on why it specifically excludes logs/HEAD from
the symlinked set ;-).

If ${branch} was 'master', does this do a checkout? I think -f
might be needed.
