From 367cec1c024c3849cb32eaac15884a4adfefe1de Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 27 May 2005 15:55:28 -0700 Subject: [PATCH] Add --pickaxe-all to diff-* brothers. When --pickaxe-all is given in addition to -S, pickaxe shows the entire diffs contained in the changeset, not just the diffs for the filepair that touched the sought-after string. This is useful to see the changes in context.
