[PATCH v3 0/5] nd/branch-show-rebase-bisect-state updates

This round fixes the design issue of read_and_strip_branch(), makes
use of jc/reflog-reverse-walk and performs cheaper sha-1 check on
detached commits.

Nguyễn Thái Ngọc Duy (5):
  wt-status: move strbuf into read_and_strip_branch()
  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
