=begin
 Fontification breaks when emacs sees a symbol like
 :'this is a symbol?'
 
 example code:
 ----------
 class EmacsExample
   :symbol
 
   'this is a test'
   'is this a test?'
   "Can this be a test"
   :'this is an error?'
 
   def bar
     @help
   end
 end

 I have a very hacked fix in ruby-font-lock-syntactic-keywords
 for 
     ;; the last $', $", $` in the respective string is not variable
     ;; the last ?', ?", ?` in the respective string is not ascii code
     ("\\(^\\|[\[ \t\n<+\(,=:]\\)\\(['\"`]\\)\\(\\\\.\\|\\2\\|[^'\"`\n\\\\]\\)*?\\\\?[?$]\\(\\2\\)"
      (2 (7 . nil))
     (4 (7 . nil)))
 
 by adding : in the above matches with space tabs L etc...
 
 See the attached patch
 
 I am not sure this is the proper fix, but it fixes the above example.
 
 Thanks,
 Zev
