 * differential:   => Phab:D907
 * milestone:  7.12.1 => 7.10.2


Comment:

 I have set the milestone to 7.10.2, as this is the last item blocking a
 full hackage round trip, resulting in 40 or so failing files out of around
 50k.

 It does require a tiny change to Haddock, but is basically just adding
 `SourceText` fields to the last places they are required.
