Hi, I have added a patch to this bug as was requested.  I'm just pinging
in case it went unnoticed as it seems to me that nothing has happened to
it in the past six days.  Anyways I guess I actually had to attach the
patch file from git-format-patch, so I'm doing that in this message.
Please excuse me for this mess, I'm quite ignorant of git, but I'll have
learned my lesson for my next patch.

Cheers!

Add an implementation of this for vc-rcs that does nothing to suppress
the message the default function adds to the vc-dir buffer (Bug#28570).
* lisp/vc/vc-rcs.el (vc-rcs-dir-extra-headers): New function.
