Comment:

 I am currently looking into this in the context of enabling cached Hadrian
 builds using Shake's caching feature. For caching to work, we need to
 accurately record all dependencies or at least to report all files
 produced withing each rule by using `produces` function:

 http://hackage.haskell.org/package/shake/docs/Development-
 Shake.html#v:produces

 I'll report back when I have a working cached build, which should bring us
 closer to fixing this issue too.
