The BzrForEmacsDevs page suggests using the "commit -m" syntax in several places.  I don't like using this because it doesn't show which files are going to be committed.  Using "commit" with an editor for the message encourages people to provide the correct log message (one line as summary, then more detailed prose), and it allows them to see what is going to be included in the change.  Many times (with git) stopped at this point, canceled the commit and went back to add another part of the change.  I think it would have prevented Bob's 30MB commit, regardless of what led to the "add".

This would be especially important in conjunction with the mirrored branches, where a commit pushes automatically (if I understand correctly).

I would suggest to only show people how to use commit with an editor.
