Summary: Bug in string literal '\c' 

Initial Comment:
Evaluation of string literal '\c' should return "\c".  However, if in IRB you type '\c'..... and it returns the following prompt to you

irb(main):001:0> '\c'
irb(main):002:0' 


However, if you enter '\d', it returns "\d" as you'd expect.

irb(main):003:0> '\d'
=> "\d"
irb(main):004:0> 


My guess is because it is expecting that '\c' is the beginning of '\cx' (which has a substitution in double-quote literals).... but there is never that additional character following '\c'

Note the following occurs when any character follows '\c'

irb(main):010:0> '\ca'
=> "\ca"
