Fair enough.  How about

    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, override the global setting of
    ‘version-control’ this way.  You can also have Emacs set
    ‘version-control’ locally whenever you visit a given file (*note File
    Variables::).
