Comment (by NeilMitchell):

 Anything that wraps {{{ghci}}} into a program that users are still
 expected to interact with is going to start having weird special cases to
 undo these changes. For my specific case of {{{ghcid}}} I can remove the
 {{{()}}} when {{{ghcid}}} itself sends a command in (no real problem), but
 I also allow the user to interact with the underlying {{{ghci}}} (via the
 {{{--test}}} flag), and there the surprising change in behaviour is going
 to be unpleasant and hard to avoid without just filtering out {{{()}}}
 lines, some of which might be deliberate.

 Any chance of getting the behaviour to omit {{{()}}} added back?
