Well, your question referred strictly to "the current buffer is in a
version controlled file".

IMHO this should not be in the texi docs, the difference between old and
new versions belongs in NEWS, "new" gets old too fast in the docs.

Maybe it wants to talk about this:

Note that if you do 
C-x v d
mark 2 files in the 'edited state, then do C-x v l
then in the log view buffer you do C-x v = you get the diff for the 2
files that were marked.
Or if you do C-x v v from the diff buffer, it will check in the 2 marked
files... 


This part:

probably wants to say that before in vc-directory you could select
multiple files, and check them in, but they were checked in one file at
a time, instead of as a group in a single command.  Just guessing
here...
