Subject: [PATCH] Emphasise the fact that the regexp and replacement in :C///
 are subjected to variable expansion before regexp parsing.  This was already
 documented if you read carefully enough, but more emphasis would have helped
 me to figure out why I needed three or four backslashes where I expected to
 need only two.
