[0/3] git-status: create config for ahead/behind calculation

Message

Koji Nakamaru via GitGitGadget June 18, 2019, 8:21 p.m. UTC

The git status builtin includes a calculation for how far the local ref is
ahead or behind the remote tracking branch. This check can be expensive, so
we already have a --[no-]ahead-behind command-line option.

This series adds two bits of functionality to the feature:

 1. Add a new status.aheadBehind config setting.
    
    
 2. Add a new advice.statusAheadBehind config setting associated with a
    warning that suggests status.aheadBehind when the calculation takes a
    long time.
    
    

We have been running with these commits in microsoft/git for a while now.
The only change I made in adapting Jeff's commits was to add the advice
config documentation.

The status.aheadBehind config setting is a candidate to be added to the
proposed "large repo" meta-config setting previously discussed [1]. I'm
putting this out for independent review as it is much smaller compared to
the potential of that series.

Thanks, -Stolee
