OK, so record/amend-record never cause the working dir to change, so 
neither does editing a hunk during those commands, which are currently the 
only places it is enabled. However, you can use darcs revert after you've 
recorded some fragments of the edited hunk, to revert the others.

I could in theory enable edit hunk for darcs revert (and perhaps darcs 
unrevert too), but I don't know what it buys you over just editing the 
file directly.
