[PATCH v3 0/5] Add --no-ahead-behind to status

[Jeff Hostetler <git@jeffhostetler.com>]

From: Jeff Hostetler <jeffhost@microsoft.com>

This is version 3 of my patch series to avoid expensive
ahead/behind calculations in status.  This version tries
to address most of the comments in V2.

I've switched back to a "status.aheadBehind" config setting
rather than in "core.*".  This has been better integrated
with the existing status_deferred_config mechanism in
builtin/commit.c and lets both status and commit inherit it.

Config values of true and false control non-porcelain formats
for compatibility reasons as previously discussed.  In the
last commit I added a new value of 2 for the config setting
to allow porcelain formats to inherit the new setting.  I've
marked this experimental for now or so that we can discuss
it.

Jeff Hostetler (5):
  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
  status: add status.aheadBehind value for porcelain output
