[PATCH v2 0/7] Renames in git-status "changed not staged" section

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

The changes in 425a28e0a4 allow new files to show up in
"git diff-files" (aka "changed but not staged") which is a problem
because status code does not handle renaming in this case.

The main change to fix this is 6/7. The interesting corner case is in
7/7 where I decided to go with a middle ground, disabling only double
renames. We have two other options to go:

 - unconditionally disable rename in wt_status_collect_changes_worktree
   which turns this 7-patch series into one patch
 - support double renames too but this may change porcelain output
   (or we have to add new output format). This could be done in a
   follow series if we want to.

Nguyễn Thái Ngọc Duy (7):
  t2203: test status output with porcelain v2 format
  Use DIFF_DETECT_RENAME for detect_rename assignments
  wt-status.c: coding style fix
  wt-status.c: rename wt_status_change_data::score
  wt-status.c: catch unhandled diff status codes
  wt-status.c: handle worktree renames
  wt-status.c: avoid double renames in short/porcelain format
