Re: vc-rename-file doesn't work for CVS

[Richard M. Stallman]

    +   Some backends do not provide an explicit rename operation to their
    + repositories.  After issuing @code{vc-rename-file}, use @kbd{C-x v v}
    + on the original and renamed buffers and provide the necessary edit
    + log.

Thanks for pointing this out.

To make this really clear, we need to tell the user how to recognize
this situation, so that he knows it is necessary to use C-x v v that
way.  Can anyone tell me the criterion or write further text saying
it?
