Junio C Hamano 29c2a3dbad Merge branch 'zj/diff-stat-smaller-num-columns'
Spend only minimum number of columns necessary to show the number of lines
in the output from "diff --stat", instead of always allocating 4 columns
even when showing changes that are much smaller than 1000 lines.

By Zbigniew Jędrzejewski-Szmek
* zj/diff-stat-smaller-num-columns:
  diff --stat: use less columns for change counts
