Junio C Hamano c2ff10c98e Merge branch 'jk/1.7.0-status'
* jk/1.7.0-status:
  status/commit: do not suggest "reset HEAD <path>" while merging
  commit/status: "git add <path>" is not necessarily how to resolve
  commit/status: check $GIT_DIR/MERGE_HEAD only once
  t7508-status: test all modes with color
  t7508-status: status --porcelain ignores relative paths setting
  status: reduce duplicated setup code
  status: disable color for porcelain format
  status -s: obey color.status
  builtin-commit: refactor short-status code into wt-status.c
  t7508-status.sh: Add tests for status -s
  status -s: respect the status.relativePaths option
  docs: note that status configuration affects only long format
  commit: support alternate status formats
  status: add --porcelain output format
  status: refactor format option parsing
  status: refactor short-mode printing to its own function
  status: typo fix in usage
  git status: not "commit --dry-run" anymore
  git stat -s: short status output
  git stat: the beginning of "status that is not a dry-run of commit"
