Now it's possible just to type 'C-x s' after customizing
'save-some-buffers-default-predicate' to 'save-some-buffers-root',
or after setting this value in project's .dir-locals.el.

If you want to use this new feature programmatically,
then just call:

  (save-some-buffers t 'save-some-buffers-root)
