The main issue is that the two branches will probably not share a common
ancestor at first.  Typically the problem is keeping track of file
identities: in the Gnus repository lisp/gnus.el will have one identity
and in Emacs's lisp/gnus/gnus.el will have another, so convincing Bzr
that those two files correspond to each other may simply be impossible
(in Arch, the identity is user-visible, set in the "arch-tag:" line or
in the .arch-ids-<file>.id file, so matching the two is not difficult).
