[PATCH v5 0/2] diff: add --compact-summary (aka nd/diff-stat-with-summary)

... and v5 fixes the commit message of 2/2 where in v4 it still mentions --stat-with-summary instead of --compact-summary. Sorry.

Nguyễn Thái Ngọc Duy (2):
  diff.c: refactor pprint_rename() to use strbuf
  diff: add --compact-summary
