share/man/man4/multicast.4
149	I'd suggest a slightly different wording: `When applied to the multicast routing socket, the .Dv MRT_DONE and .Dv MRT6_DONE socket options disable multicast forwarding in the kernel:`
158	Closing the socket has the same effect, we could mention that here too.

Agree with markj. Nit: commit message should be "multicast.4: Fix disabling multicast forwarding". "multicast(4)" could refer to changing the logic of the driver, but "multicast.4" clearly refers only to the manual page.

Been spring-cleaning my cluster home directory, as I only regained access for the first time in nearly 10 years this morning UK time. This commit probably has some relevant history lessons.
