Turn errors into warnings (bzr rm FILE -- stops on error)

[Jari Aalto]

Would it be possible to add (global?) option to turn on error into warning.
Useful for removing accidents from the repository:

      bzr add ..
      bzr add ...

      <time passes, oops>

      $ bzr rm $(bzr inventory | grep '\.svn')
      bzr: ERROR: .svn/all-wcprops is not versioned

The command does not remove any files due to the error. I would like
ignore any of those errors during "rm".
