worktree: new place for "git prune --worktrees"
Commit 23af91d (prune: strategies for linked checkouts - 2014-11-30) adds "--worktrees" to "git prune" without realizing that "git prune" is for object database only. This patch moves the same functionality to a new command "git worktree". Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com>
