Did you `bzr update' your local mirror first? Maybe `bzr missing' does
not work with bound branches.

My trunk mirror is not bound, and after a `bzr pull' the `bzr missing'
method above shows that the oldest revision that the emacs-23 branch is
missing is

revno: 99635 [merge]
committer: Stefan Monnier <address@hidden>
branch nick: trunk
timestamp: Wed 2010-03-10 00:18:51 -0500
message:
  Merge pending branch

which means that the branch was created from revision 99634.

No. Branching is copying the full history. You get a clone of the
original branch (actually, there is a `clone' bzr command that is
synonymous of `branch') The original branch does not reflect that a
clone was spawned, nor the cloned branch remembers the tip revision.

That's reasonable.
