Comment (by vivian):

 You could pass a function that tells you whether it needs another line:
 {{{
 getMultiLine :: Monad m => (String -> m Bool) -> InputT m [String]
 getMultiLine test = do
   input <- getInputLine
   another <- lift $ test input
   if another
     then do
       rest <- getMultiLine test
       return $ input : rest
     else return input
 }}}

 This would help with an issue with GHC #4316 in that we might want to
 merge the strings into one history entry.  That also introduces the issue
 of haskeline presenting multiline commands (those containing "\n") from
 the history.
