If you have commit access, please setup CIA in your Bazaar config so those in IRC receive notification of your commits.
In ~/.bazaar/bazaar.conf, add "cia_send_revno = true". Optionally, you can also add "cia_user = myusername" if you'd like CIA service to use a specific account (for statistical purpose).
In the .bzr/branch/branch.conf of your checkout branch, "set nickname = /path_to_this_branch" and "cia_project = GNU GRUB".
Additionally, please set cia_send_revno in the [DEFAULT] section of your ~/.bazaar/bazaar.conf. E.g.:
[DEFAULT] cia_send_revno = true
Remember to install cia-clients (Debian/Ubuntu package) to be able to use CIA.
Keep in mind Bazaar sends notifications for all commits to branches that have this setting, regardless of whether they're bound branches (checkouts) or not. So if you make local commits in a non-bound branch and it bothers you that others can read them, do not use this setting.
