+Subject: [PATCH] Mark our explicit fall through so -Wextra will work in gcc 7
+
+gcc 7 introduces detection of fall-through behavior in switch/case
+statements, and will warn if -Wimplicit-fallthrough is present and there
+is no comment stating that the fall-through is intentional.  This is
+also triggered by -Wextra, as it enables -Wimplicit-fallthrough=1.
+
+This patch adds the comment in the one place we use fall-through.
