  "message": "switch: make --orphan switch to an empty tree\n\nSwitching and creating branches always involves knowing the\n\u003cstart-point\u003e to begin the new branch from. Sometimes, people want to\ncreate a new branch that does not have any commits yet; --orphan is a\nflag to allow that.\n\n--orphan overrides the default of HEAD for \u003cstart-point\u003e instead causing\nus to start from an empty history with all tracked files removed from\nthe index and working tree. The use of --orphan is incompatible with\nspecifying a \u003cstart-point\u003e.\n\nA note on the implementation. An alternative is just create a dummy\ncommit in-core with empty tree and switch to it. But there\u0027s a chance\nthe commit\u0027s SHA-1 may end up somewhere permanent like reflog. It\u0027s best\nto make sure \"commit\" pointer is NULL to avoid it.\n\nSigned-off-by: Nguyễn Thái Ngọc Duy \u003cpclouds@gmail.com\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
