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 ;-).

Show 6 quoted lines

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