It seems the set_repeat_move_to_character_motion command has a problem under ST3:
>>> view.run_command('set_repeat_move_to_character_motion')
TypeError: run_() takes 2 positional arguments but 3 were given
This breaks the ; and , shortcuts of the Vintage mode, which are mapped to this command.
Note: this is on the Linux 3008 build, running on Ubuntu 12.10 64bits
