bzr merge-upstream seems to ignore -r <rev>

[Didier Roche-Tolomelli]

It doesn't seem to happen everytime on every branch, but here is a non working testcase:

clutk trunk rev 213 (from lp:clutk)
clutk-packaging rev 194 (from lp:~unity-team/clutk/packaging)

As you can see, the release is in rev 212. 213 is just post-release bump.
So, I want to release with rev 212 imported in my packaging branch as merge-upstream.

$ bzr merge-upstream -r -2 ../clutk-0.3.32.tar.gz ../clutk --version 0.3.32
$ debcommit
-> rev 213 from clutk trunk has been imported too

bzr merge-upstream -r 212 ../clutk-0.3.32.tar.gz ../clutk --version 0.3.32
bzr merge-upstream -r tag:0.3.32 ../clutk-0.3.32.tar.gz ../clutk --version 0.3.32
Same with those syntax.

So, right now, I bzr branch -r -2 clutk-trunk clutk-release
and do merge-upstream from clutk-release as a workaround.
