Subject: Rework hooke.command.Command.handle_arguments (again :p).
X-Git-Url: http://git.tremily.us/?p=hooke.git;a=commitdiff_plain;h=0c4e16451e80bd81e7e99b95c46bf9de9601f4d0

Rework hooke.command.Command.handle_arguments (again :p).

Previous implementation didn't set params[name] when
  num_provided == 0 and argument.callback != None
