Heh.. I should have checked mails more often while coding ;-)

This is what I got, which is slightly different from your series
because I want to call set_git_dir() just one time (by
setup_git_directory) and never again. I think the API looks close
enough.

I will probably rework on top of your chdir-notify instead (and let
yours to be merged earlier)

Note, this one is built on a strange base, which is a merge of 'next'
and 'sb/object-store' (I needed 'next' and Junio would have another
evil merge if 'sb/object-store' was not in the base).

Nguyễn Thái Ngọc Duy (8):
  strbuf.c: add strbuf_ensure_trailing_dr_sep()
  strbuf.c: reintroduce get_pwd_cwd() (with strbuf_ prefix)
  trace.c: export trace_setup_key
  setup.c: introduce setup_adjust_path()
  setup.c: allow other code to be notified when $CWD moves
  environment.c: adjust env containing relpath when $CWD is moved
  repository: adjust repo paths when $CWD moves
  refs: adjust main repo paths when $CWD moves
