Thanks, it's also possible I'm just too confused/tired/dumb to ask
a clear question.

But not also decide to pull from DEST, right? i.e. it
push and pull's --remembers are independent?

That's the thing - Are you skipping a step here? At least, you've
got no _manifest_ local mirror of UB. I suppose the data's basically 
there underneath.  Why aren't I implicitly or explicitly making a local 
remote-tracking branch RB mirroring UB, then local branch LB ?  Or 
alternatively, if LB is the local mirror of UB, why am I sending changes 
from it - Why am I changing it in the first place? See below.

Well, exactly, hence remote-tracking branches.

*** Well, see, that strongly suggests to me the local branch "trunk" 
_is_ the bzr analog of remote-tracking branch:

"""Now, create a branch called trunk that will just be a mirror of the 
mainline. You’ll never do any development in this branch; its job is 
just to reflect the upstream master:"""

"""The --no-tree option prevents an automatic checkout of the source 
tree. This has two functions. It saves some space. More important, it 
reduces the temptation to edit sources in this branch to almost nothing 
— so that you don’t accidentally commit any local changes on it."""

*** Except for the bit where someone ...commits local changes on it... 
Wait, what?

Fortunately, I'm not an upstream committer, I'll presumably be sending 
or asking upstream committers to pick stuff from my public tree, but 
still, I'm clearly missing something.

"""Alternatively, if you are a committer, you may want to push to the 
upstream master.

      cd $DEVHOME/emacs/trunk/
      bzr pull
      bzr merge ../quickfixes

and then commit

      bzr commit -m "Merge: fix bla bla bla (closes Bug #1)."
which automatically pushes all your new commits to the upstream master, 
because the mirror is set up as bound branch.
"""

*** why is this happening on branch trunk and not a branch
my-trunk branched from trunk?  Can it, say, happen on such a branch 
my-trunk (not quickfixes, given dire warnings about history messing up 
if you do that) without ill effect, just to stop my brain hurting? Or
is that just as apparently bad as pushing from quickfixes would be?
