At least for CEDET, I can surely tell that we won't get fully identical
branches, at least not in the foreseeable future. This is mainly due to

- compatibility code we keep for older Emacs versions (we will drop
  Emacs22 support for our new development branch, but there are still
  things like cedet-called-interactively-p for Emacs 23.1),

- features that currently depend on defadvice or other hacks, but that
  are very useful for hacking on CEDET (generating properly linked help
  buffers for EIEIO methods and classes, for instance),

- minor packages which are not needed or wanted in Emacs proper (like

- things we don't have papers for and are in our contrib directory,

- EIEIO is part of CEDET but not in lisp/cedet but in lisp/emacs-lisp (a
  similar problem exists with Speedbar, but that is in Emacs for quite
  some time now and most development happens there anyway).

It's not as bad as it sounds; most of the differences are minor or are
at least well separated, but still - you need to cherry-pick commits.
