How about this?

  [1/5] init: correct re-initialization from a linked worktree
  [2/5] init: call set_git_dir_init() from within init_db()
  [3/5] init: kill set_git_dir_init()
  [4/5] init: do not set unnecessary core.worktree
  [5/5] init: kill git_link variable

I went a bit further, merging set_git_dir_init() back to init_db() so
I can kill "git_link" variable cleanly in 5/5. 3/5 does make init_db()
a bit longer, but not to the alarming level yet. By 4/5,
set_git_dir_init() is gone, so init_db() just needs to save and pass
original_git_dir down to needs_work_tree_config().
