[PATCH v4 0/8] status: V2 porcelain status

This patch series adds porcelain V2 format to status. This provides detailed information about file changes and about the current branch.

The new output is accessed via:
    git status --porcelain=v2 [--branch]

Relative to the V3 patch series, in this V4 patch series I've updated Documentation/git-status.txt for clarity.

Jeff Hostetler (8):
  status: rename long-format print routines
  status: cleanup API to wt_status_print
  status: support --porcelain[=<version>]
  status: per-file data collection for --porcelain=v2
  status: print per-file porcelain v2 status data
  status: print branch info with --porcelain=v2 --branch
  git-status.txt: describe --porcelain=v2 format
  status: tests for --porcelain=v2
