+ * When "git log" gets "--simplify-merges/by-decoration" together with
+ "--first-parent", the combination of these options makes the
+ simplification logic to use in-core commit objects that haven't
+ been examined for relevance, either producing incorrect result or
+ taking too long to produce any output. Teach the simplification
+ logic to ignore commits that the first-parent traversal logic
+ ignored when both are in effect to work around the issue.

+ * "git add" allows adding a regular file to the path where a
+ submodule used to exist, but "git update-index" does not allow an
+ equivalent operation to Porcelain writers.

+ * "git diff --no-index" did not work with pagers correctly.
+ (merge af63b54 jk/diff-no-index-pager later to maint).
+
+ * "git diff COPYING HEAD:COPYING" gave a nonsense error message that
+ claimed that the treeish HEAD did not have COPYING in it.
