[PATCH v2 0/8] nd/multiple-work-trees follow-ups

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

This fixes all comments from v1. I still keep the long advice when
'git checkout' fails because another branch is locked, because it's
easy(*) to disable the advice. Two more fixes found today. The test
breakages on Windows have to wait until somebody on Windows jumps in.

(*) although I start to want an advice.nothing config that disables
all advice..

Nguyễn Thái Ngọc Duy (8):
  gitrepository-layout.txt: s/ignored/ignored if/
  checkout: no need to call check_linked_checkouts if head_ref is NULL

  checkout: no auto-detach if the ref is already checked out
  checkout --to: fix dangling pointers in remove_junk()
  environment.c: fix incorrect git_graft_file initialization
  checkout: prefix --to argument properly when cwd is moved
  checkout --to: do not touch existing target directory
