[PATCH v2 0/4] nd/branch-show-rebase-bisect-state updates

Since the previous round:

 - reflog format change is dropped
 - almost always show "HEAD detached from/at xxx" instead of
   "currently not on any branch", where "xxx" is either a ref, or an
   abbreviated sha-1

I wanted to introduce something like @{-1:to} that resolves the "to" sha-1 in reflog, in addition to @{-1} which resolves the "from" part. But the syntax looks ugly so I dropped it. Meanwhile people could do

git log -1 -g --grep-reflog checkout --pretty=format:%h

to retrieve the same info.

Nguyễn Thái Ngọc Duy (4):
  wt-status: split wt_status_state parsing function out
  wt-status: move wt_status_get_state() out to wt_status_print()
  status: show more info than "currently not on any branch"
  branch: show more information when HEAD is detached
