Merge branch 'nd/ita-wt-renames-in-status' into maint

"git status" after moving a path in the working tree (hence making
it appear "removed") and then adding with the -N option (hence
making that appear "added") detected it as a rename, but did not
report the  old and new pathnames correctly.

* nd/ita-wt-renames-in-status:
  wt-status.c: handle worktree renames
  wt-status.c: rename rename-related fields in wt_status_change_data
  wt-status.c: catch unhandled diff status codes
  wt-status.c: coding style fix
  Use DIFF_DETECT_RENAME for detect_rename assignments
  t2203: test status output with porcelain v2 format
