Merge branch 'nd/multiple-work-trees'

"git checkout [<tree-ish>] <paths>" spent unnecessary cycles
checking if the current branch was checked out elsewhere, when we
know we are not switching the branches ourselves.

* nd/multiple-work-trees:
  worktree: new place for "git prune --worktrees"
  checkout: don't check worktrees when not necessary
