Re: [PATCH] clone: handle unborn branch in bare repos

When cloning a repository with an unborn HEAD, we'll set the local HEAD
to match it only if the local repository is non-bare. This is
inconsistent with all other combinations:

  remote HEAD       | local repo | local HEAD
  -----------------------------------------------
  points to commit  | non-bare   | same as remote
  points to commit  | bare       | same as remote
  unborn            | non-bare   | same as remote
  unborn            | bare       | local default

So I don't think this is some clever or subtle behavior, but just a bug
in 4f37d45706 (clone: respect remote unborn HEAD, 2021-02-05). And it's
easy to see how we ended up there. Before that commit, the code to set
up the HEAD for an empty repo was guarded by "if (!option_bare)". That's
because the only thing it did was call install_branch_config(), and we
don't want to do so for a bare repository (unborn HEAD or not).

Readding this and 4f37d45706, I tend to agree. Thanks for a
straightforward patch, fix, and test :-).
