[MERGE REVIEW] New output for bzr info with API test case

[Martin Pool]

+1, looks good.

Some more suggestions:

  - the help string for bzr info (in cmd_info) should say more about  
what will be displayed

  - I think these changes mean that bzr info will always try to  
access the repository, and so the command won't work when you're in  
e.g. a checkout and not connected.  Perhaps there could be a --local  
option.

I'll merge in what you already have.
