sounds good; an editor is useful when you may want multi-line variables, 
but you would probably rarely use that

that's as easy as throwing BzrCommandError

this is a bit more complicated, due to having several config stores

again, complicated; I'll have to subclass BranchConfig for the 2 above 
features, because there is no "dump" and "remove" functionality

unless there is some class I don't know about (quite possible, 
actually), there is no support for subcommands with specific options and 
aliases, so this would need to be implemented by hand; and it'll grow 
big, and I'm horrified about writing tests, because I've never done that 
(never needed), so I wouldn't know where to start and where to finish :)
