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
Diffstat (limited to 'diff.c')
