[PATCH 0/3] Minor fixes on 'git worktree'

This fixes two things:

 - make sure the first item is always the main worktree even if we
   fail to retrieve some info

 - keep 'worktree list' order stable (which in turn fixes the random
   failure on my 'worktree-move' series

Nguyễn Thái Ngọc Duy (3):
  worktree.c: zero new 'struct worktree' on allocation
  get_worktrees() must return main worktree as first item even on error
  worktree list: keep the list sorted
