[Chong Yidong]

Hi Phil,

If you have time, could you take a look at this bug report?  Thanks.

  The syntax  %{#{'?'}} , while legal (it is equivalent to '?'), makes
  all the following text appear in font-lock-string-face.

  The same happens with %{#{"?"}} , and seems to rise from the ?" or ?'
  part: if I put a space (or whatever) after the ? , things work.

  Real life example (from the sources of rubyonrails):

  self.class_eval %{
    def self.#{method_id}(*args)
      guard_protected_attributes = false

      if args[0].is_a?(Hash)
        guard_protected_attributes = true
        attributes = args[0].with_indifferent_access
        find_attributes =
        attributes.slice(*[:#{attribute_names.join(',:')}])
      else
        find_attributes = attributes = 
construct_attributes_from_arguments([:#{attribute_names.join(',:')}], args)
      end

      options = { :conditions => find_attributes }
      set_readonly_option!(options)

      record = find_initial(options)

       if record.nil?
        record = self.new { |r| r.send(:attributes=, attributes, 
guard_protected_attributes) }
        #{'yield(record) if block_given?'}
        #{'record.save' if instantiator == :create}
        record
      else
        record
      end
    end
