  * version:  1.2.3.0 => HEAD

Comment:

 For installed packages index, we should parse the output of `ghc-pkg dump`
 lazily. See #311.

 All it needs is to split on `"\n---"` as we do now, but then instead of
 directly parsing, we should extract only the name and version fields and
 then parse the rest lazily.
