git-worktree currently conflates setting of HEAD in the new worktree and initial worktree population into a single git-checkout invocation which requires git-checkout to have special knowledge that it is operating on a newly created worktree. The eventual goal is to rid git-checkout of that overly-intimate knowledge.
Once these operations are separate, git-worktree will no longer be able to delegate to git-branch the setting of the new worktree's HEAD to the desired branch (or commit, if detached). Therefore, make git-worktree itself responsible for setting up HEAD as either a symbolic reference, if associated with a branch, or detached, if not.
