The code to traverse objects for reachability, used to decide what objects are unreferenced and expendable, have been taught to also consider per-worktree refs of other worktrees as starting points to prevent data loss. * nd/per-worktree-ref-iteration: git-worktree.txt: correct linkgit command name reflog expire: cover reflog from all worktrees fsck: check HEAD and reflog from other worktrees fsck: move fsck_head_link() to get_default_heads() to avoid some globals revision.c: better error reporting on ref from different worktrees revision.c: correct a parameter name refs: new ref types to make per-worktree refs visible to all worktrees Add a place for (not) sharing stuff between worktrees refs.c: indent with tabs, not spaces
