I think the break command is a bit different to the others as it stops 
the rebase and so the user may want a reminder of what they were 
planning to do when it stopped. The other commands just pick a commit or 
run a command so I'm not sure what the comment would be for.

That's a neat idea, maybe we should just add some documentation 
suggesting users do that?
