[PATCH v8 0/3] Cloning with remote unborn HEAD

Peff sent a review (which I don't see in lore.kernel.org/git, but I do see it in my inbox); here's v8 in response to that.

As you can see from the range-diff, there are just minor changes to v7 (wording in documentation and a memory leak fix).

Jonathan Tan (3):
  ls-refs: report unborn targets of symrefs
  connect, transport: encapsulate arg in struct
  clone: respect remote unborn HEAD
