Template Haskell: Quoting single letter identifier leads to a parse error at end of input.

To reproduce the bug with ghci:

Prelude> :set -XTemplateHaskell
Prelude> let a = 1
Prelude> :t 'a

<interactive>:1:1:
    lexical error in string/character literal at character 'a'

As a module, the following source code works if the last line has no newline:

{-# LANGUAGE TemplateHaskell #-}
a = 1
b = 'a
