I created a branch for backward-incompatible changes, it's in
/branches/multiboot2.

This does NOT mean that backward-incompatible changes are postponed.  The
draft in /branches/multiboot2 is already implemented in latest GRUB trunk.
Further changes to this draft can be implemented in GRUB inmediately.

So the workflow is basically:

  - Non-incompatible ammendments can go in /trunk/multiboot.

  - Incompatible ammendments can go in /branches/multiboot2.  This branch
    can (and should) be periodically resynced with /trunk/multiboot.

  - In both cases, ammendments should be accompanied by changes to the
    example kernel (when this makes sense, of course).

  - The master copies of multiboot.h and multiboot2.h are in those
    respective branches.  GRUB shouldn't need to diverge from them, as
    all the GRUB-specific declarations are split in <grub/*> namespace
    already.
