I think this is important.  It completes what .dir-locals.el can do.
Without it, you cannot use .dir-locals.el for any of the *vc* buffers.
The line I cite above is used to turn on whitespace-mode in *vc diff*.

It's a new feature.  If all programming modes are derived from
`prog-mode', then one can do:
(add-hook 'prog-mode 'flyspell-prog-mode)
to turn on the fly spell checking for comments and strings in all programming modes.
This is not complete on the trunk either.  So if you have an
aggressive schedule to get the release out, we can let this one go.
