[racket] SRFI 19 string->date: Error reading dates

The crashes are unrelated to the srfi/19, you should fill another bug
report for that :).

A simpler example (inspired by the reply of Alexis King) is:

#lang racket
(+ (values) 777)

------
Error:
result arity mismatch;
 expected number of values not received
  expected: 1
  received: 0
  values...:
------

The problem is in the ellipsis after "values". If you hoover the mouse
over them you got an error in the console:
>>>   setting cursor to #(struct:object:cursor% ...)

if you copy text that include the ellipsis you get:
>>>   write method in ellipsis-snip%: arity mismatch;
>>>    the expected number of arguments does not match the given number
>>>     expected: 1
>>>     given: 2
>>>     arguments...:
>>>      '()
>>>      #<output-port:string>
