Commands are the heart of the command-line bzr interface.

The command object mostly handles the mapping of command-line

182
Commands normally don't have any state. All their arguments are
183
passed in to the run method. (Subclasses may take a different
184
policy if the behaviour of the instance needs to depend on e.g. a
185
shell plugin and not just its Python class.)

replace - put in a bogus character (typically '?')
