With the previous Emacs tips example the kernel style was made available
for files in the kernel-tree only. This patch updates the tip to add
separate cc-mode indent style; it makes the kernel style easily
available for any filetype mode that is managed by the Emacs cc-mode.
We also fix the filename regexp in the example: Elisp function
buffer-file-name returns full pathname, not a path relative to user's
home directory. Hence a tilde (~) can't be used to refer to home
directory (as the previous code did).

This will make emacs go better with the kernel coding style for C
-files below ~/src/linux-trees.
+files which pathname matches src/linux-trees.
But even if you fail in getting emacs to do sane formatting, not
everything is lost: use "indent".
