Comment (by simonpj):

 I do rather agree with you, but it's a user question so let's get more
 user feedback.

 A very simple, but brutal, way to achieve this would be to aggregate error
 messages that were identical, as strings.  We don't keep them as data, so
 the string (or rather `SDoc`) is all we have to do on.

 You could try this in `printMsgBag` in `ErrUtils`.
