How about this one:
   ** Directory local variables can apply to file-less buffers.
   For example, adding "(diff-mode . ((mode . whitespace)))" to your
   .dir-locals.el file, will turn on `whitespace-mode' for *vc-diff* buffers.
The code change itself is small, and only touches one or two
functions.

How about the changes to make major modes derive from `prog-mode'?

Copy the files from trunk over to the branch.  AFAIR there's nothing
that depends on changes to the core, so just copying should be fine.
