Comment (by MtnViewMark):

 This is a hard one for several reasons:

 1) The logic for doing a rebuild of the haddock index is in the cabal
 executable (from the cabal-install package, not the library from Cabal).
 This logic is a bit tricky and hard to recreate by hand. Cabal doesn't
 give a command to invoke it directly. I have some shell scripts that
 recreate it more or less. I think this logic should be moved to haddock.

 2) There are really two haddock indexes that should be updated: a) The
 --global index (assuming there is one) that only includes the packages
 installed --global. b) The user's local index, since even though their
 packages didn't change, their index usually includes all the --global
 packages. (a) has the issue that it probably requires sudo privileges. (b)
 leaves other users' in need of an update.
