A little style issue here on the side, if I may. You don't need to use
(++) to join multiline string literals.

text = "If you want to have multiline string literals \
\in your source code, you can break them up with \
\backslashes. Any whitespace characters between \
\two backslashes will be ignored."

(The Haskell 98 Report calls them backslants.)
