Okay, I guess "override the global setting" is too confusing.  Rmail
only sets it locally.  Does this work better:

    The usual way to set this variable is globally, through your init
    file or the customization buffer.  However, you can set
    ‘version-control’ locally in an individual buffer to control the
    making of backups for that buffer’s file (*note Locals::).  Some
    packages, such as Rmail, do this.  You can also have Emacs set
    ‘version-control’ locally whenever you visit a given file (*note
    File Variables::).
