In repo controller entry action, show the page for the file even if it's binary (so user still has access to history etc links). This makes it possible to use the entry action as the default when a file is clicked on

module CodeRay
module Encoders
  
  # Returns the number of tokens.
  # 
  # Text and block tokens are counted.
  class Count < Encoder
    
    register_for :count
    
  protected
    
    def setup options
      super
      
      @count = 0
    end
    
    def finish options
      output @count
    end
    
  public
    
    def text_token text, kind
      @count += 1
    end
    
    def begin_group kind
      @count += 1
    end
