bzr bisect reset
or simply delete the entire branch if you created it just for this.

+* Commit emails
+
+** Old method: bzr-hookless-email
+https://launchpad.net/bzr-hookless-email
+
+Runs hourly via cron. Must ask Savannah admins to enable/disable it
+for each branch. Stores the last revision that it mailed as
+last_revision_mailed in branch.conf on the server. Breaks with bzr 2.6:
+
+http://lists.gnu.org/archive/html/savannah-hackers-public/2013-05/msg00000.html
+
+Fix from https://bugs.launchpad.net/bzr-hookless-email/+bug/988195
+only partially works. Breaks again on every merge commit:
+
+https://lists.ubuntu.com/archives/bazaar/2013q2/075520.html
+http://lists.gnu.org/archive/html/savannah-hackers-public/2013-05/msg00024.html
+
+You can force it to skip the merge commit by changing the value for
+last_revision_mailed, eg:
+
+bzr config last_revision_mailed=xfq.free@gmail.com-20130603233720-u1aumaxvf3o0rlai -d bzr+ssh://USERNAME@bzr.savannah.gnu.org/emacs/trunk/
+
+** New method: bzr-email plugin
+https://launchpad.net/bzr-email
+http://lists.gnu.org/archive/html/savannah-hackers-public/2013-06/msg00007.html
+
+Runs on commit. Projects can enable it themselves by using `bzr
+config' to set post_commit_to option for a branch. See `bzr help email'
+(if you have the plugin installed) for other options.
+
+The From: address will be that of your Savannah account, rather than
+your `bzr whoami' information.
+
+Note: if you have the bzr-email plugin installed locally, then when
+you commit to the Emacs repository it will also try to send a commit
+email from your local machine. If your machine is not configured to
+send external mail, this will just fail. In any case, you may prefer
+to either remove the plugin from your machine, or disable it for Emacs
+branches. You can do this either by editing branch.conf in your Emacs
+branches, to override the server setting (untested; not sure this
+works), or by adding an entry to ~/.bazaar/locations.conf:
+
+ [bzr+ssh://USERNAME@bzr.savannah.gnu.org/emacs/*/]
+ post_commit_to = ""
+
+You have to use locations.conf rather than bazaar.conf because the
+latter has a lower priority than branch.conf.
