* "git diff -M --cached" used to use unmerged path as a possible rename
source candidate, which made no sense.
+ * "git format-patch" did not quote RFC822 special characters in the
+ email address (e.g From: Junio C. Hamano <jch@example.com>, not
+ From: "Junio C. Hamano" <jch@example.com>).
+
+ * "git format-patch" when run with "--quiet" option used to produce a
+ nonsense result that consists of alternating empty output.
+
* "git merge-one-file" did not honor GIT_WORK_TREE settings when
handling a "both sides added, differently" conflict.
+ * "git mergetool" did not handle conflicted submoudules gracefully.
+
* "git-p4" (in contrib) used a wrong base image while merge a file that
was added on both branches differently.
