% ghc --numeric-version
7.4.2
% ghc-mod expand Fuga.hs
Fuga.hs:(6,8)-(10,2): Splicing expression
    "\
    \hoge\
    \fuga\
    \piyo"
  ======>
    "\
    \hoge\
    \fuga\
    \piyo"
Fuga.hs:13:8-31: Splicing expression
    " hoge fuga piyo " ======> " hoge fuga piyo "

% ghc --numeric-version
7.6.1
% ghc-mod expand Fuga.hs
Fuga.hs:(6,8)-(10,2): Splicing expression    "\    \hoge\    \fuga\    \piyo"  ======>    "\    \hoge\    \fuga\    \piyo"
Fuga.hs:13:8-31: Splicing expression    " hoge fuga piyo " ======> " hoge fuga piyo "

With 7.6.x, the output contains NUL characters instead of LF. Related to #92?

I'm not sure what is a correct solution for this. But I guess the -b option helps you.

% ghc-mod expand -b "\n" Fuga.hs
