[PATCH] t1900: cover linked worktrees and separate git dirs

[Jialong Wang <jerrywang183@yahoo.com>]

Add repo-info coverage for repositories accessed through a linked\nworktree and through a worktree created with --separate-git-dir.\n\nThese layouts are already supported by the current implementation, but\nare not exercised by t1900-repo-info.sh yet. Cover both the lines and\nnul output formats for layout.bare and layout.shallow in these cases.
