Yi.Command.Help

Help command support This module uses Yi.Eval.describeNamedAction to show whatever information about particular action is available from current evaluator (ghciEvaluator currently presents only type.) TODO: Would be nice to show excerpt from Haddock documentation in the future.

If given no arguments, the help index is shown (using getAllNamesInScope).

Please do not try to show descriptions for the whole index, as our interface to GHCi is too slow.
