[PATCH v5 3/4] status: update short status to respect --no-ahead-behind




From: Jeff Hostetler <jeffhost@xxxxxxxxxxxxx>

Teach "git status --short --branch" to respect "--no-ahead-behind"
parameter to skip computing ahead/behind counts for the branch and
its upstream and just report '[different]'.
