+   responding to "fetch/clone" via the uploadpack.packObjectsHook.
+   (merge 20b20a2 jk/upload-pack-hook later to maint).
+
+ * Teach format-patch and mailsplit (hence "am") how a line that
+   happens to begin with "From " in the e-mail message is quoted with
+   ">", so that these lines can be restored to their original shape.
+   (merge d9925d1 ew/mboxrd-format-am later to maint).
+
+ * "git repack" learned the "--keep-unreachable" option, which sends
+   loose unreachable objects to a pack instead of leaving them loose.
+   This helps heuristics based on the number of loose objects
+   (e.g. "gc --auto").
+   (merge e26a8c4 jk/repack-keep-unreachable later to maint).

+ * "log --graph --format=" learned that "%>|(N)" specifies the width
+   relative to the terminal's left edge, not relative to the area to
+   draw text that is to the right of the ancestry-graph section.  It
+   also now accepts negative N that means the column limit is relative
+   to the right border.

+
+ * Formats of the various data (and how to validate them) where we use
+   GPG signature have been documented.
+   (merge cc6ee97 mg/signature-doc later to maint).
+
+ * A new run-command API function pipe_command() is introduced to
+   sanely feed data to the standard input while capturing data from
+   the standard output and the standard error of an external process,
+   which is cumbersome to hand-roll correctly without deadlocking.
+
+   The codepath to sign data in a prepared buffer with GPG has been
+   updated to use this API to read from the status-fd to check for
+   errors (instead of relying on GPG's exit status).
