[PATCH v4 0/4] Add --no-ahead-behind to status

From: Jeff Hostetler <jeffhost@microsoft.com>

This is version 4 of my patch series to avoid expensive ahead/behind calculations in status. This version removes the last commit containing the experimental config setting. And removes the undefined return values for the nr_ahead/nr_behind arguments as discussed on the mailing list.

This version does not address "git branch -vv", but that requires passing data across the for-each-ref barrier and that seemed beyond the scope of this task.

Jeff Hostetler (4):
  stat_tracking_info: return +1 when branches not equal
  status: add --[no-]ahead-behind to status and commit for V2 format.
  status: update short status to respect --no-ahead-behind
  status: support --no-ahead-behind in long format
