Code review comment for lp:~jelmer/bzr/private-update-revisions

It merged a branch which has landed since this MP was created, which makes the diff for this branch appear larger than it actually is.

The other branch that was merged (and removes fetch_spec as argument) can be found here: https://code.launchpad.net/~jelmer/bzr/move-interbranch-fetch2/+merge/59204
