escape quotes in strings and characters

[porcuquine]

The second entered expression fails to parse, but it is the printed representation returned from the first. The returned value should include the escape character (backslash).

lurk-user> '\''
[1 iteration] => '''
lurk-user> '''
; hangs
;; 

The same issue is demonstrated with strings.

lurk-user> ""
[1 iteration] => ""
lurk-user> """
; hangs
