explict export lists Eliminated some dead code. In other cases, exported a currently unused function, since it was a logical part of the API. Of course this improves the API documentation. It may also sometimes let ghc optimize code better, since it can know a function is internal to a module. 364 modules still to go, according to git grep -E 'module [A-Za-z.]+ where' 2019-11-21 15:38:06 -04:00			`module Utility.PID (PID, getPID) where`
