Comment (by judah):

 My initial thoughts: we could add a new action
 getMultiLine :: [String] -> InputT m [String]
 where the input to the function is the initial text to be edited.

 However, what the ghci tickets are trying to achieve is that the user
 enters a single line of text, ghci notices via layout rules that the line
 is incomplete, and continues it in a multi-line input.  If you used
 getInputLine followed by getMultiLine, the first row would be repeated,
 which is probably not the best UI.  So getInputLine and getMultiLine would
 have to interact, and I'm not sure how that could work without making
 things much more complicated.
