Yes, for the 1 extra revision. I don't know from where come the missing
27 revisions if you already merged those.

You can see the stuff you merged on the last commit on quickfixes/ with

bzr log -n1 -l30

(show one level of merge history, 30 commits maximum)

See if the revisions listed there are the same `bzr missing' lists.

Omitting the "27 missing revisions" and going back to the scenario you
described on your original post, a solution for this is to push that
extra revision into trunk. It is not the right solution, though, if your
`trunk' branch is intended to be a mirror of upstream's `trunk'. Other
solution is to uncommit, if you didn't commited more stuff to
quickfixes/ :

bzr uncommit
bzr revert

A brute-force solution is to delete the quickfixes/ branch (`rm -rf
quickfixes/' will do fine) and create another with the same name. This
is acceptable as far as you have no useful local commits there, of

It depends. Sometimes the right thing is to pull, sometimes you want to
merge. For your local mirror of upstream's trunk, you always want to
pull. For the rest of the branches, if you already have local commits,
`merge' is your only option. Once you send the local commits upstream,
you can pull again.
