[PATCH 0/4] worktree: Support `--orphan` when creating new worktrees

While working with the worktree based git workflow, I realised that setting up a new git repository required switching between the traditional and worktree based workflows. Searching online I found a SO answer [1] which seemed to support this and which indicated that adding support for this should not be technically difficult.

Note: This is my first patchset for git so please let me know if there's anything
I should do differently to improve contributions in the future.

This patchset has three parts:

  * adding `-B` to the usage docs (noticed during dev and it seemed too small
    to justify a separate submission)
  * switching from `git reset --hard` to `git checkout` for worktree checkout
  * adding orphan branch functionality (as is present in `git-checkout`)
    to `git-worktree-add`
