Let's call these actual revision numbers, since that's what you'll use
in the UI::

    Revision 1
    Revision 2
    Revision 3

Revert the changes you decide you don't like (to get the working tree in
the right state), then commit the working tree state describing what you
did.

    $ bzr revert --revision 0..1
    $ bzr commit --message "Fix blunder introduced in the flooble module."

Unfortunately, the ‘revert’ command doesn't — in Bazaar 1.17 which I'm
using — support the common ‘--change N’ option (which is effectively a
shortcut for the above one-step range of revisions).
