Error on single export

[ExternalReality]

It appears that a situation can arise where haskell-emacs-init expects a module to export a list of symbols and errors out in the case when a compiled module only exports one.

module Mod where -- OK (in the case where nothing exported at all)
module Mod where -- OK (in the case where multiple things are exported)
module Mod (x, y) where -- OK
module Mod (x) where -- Not OK

emacs messages the following when encountering the error: error in process filter: when expecting a list, encountered string instead

Ah, I'll have to dig into the elisp part... I'll fix it this week, thanks for reporting!
