From f34a9416ab9efa13a53a31cabd9061d583aaba7e Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Tue, 12 Aug 2008 10:45:59 +0200 Subject: [PATCH] filter-branch: use --simplify-merges Use rev-list --simplify-merges everywhere. This changes the behaviour of --subdirectory-filter in cases such as O -- A -\ \ \ \- B -- M where A and B bring the same changes to the subdirectory: It now keeps both sides of the merge. Previously, the history would have been simplified to 'O -- A'. Merges of unrelated side histories that never touch the subdirectory are still removed.
