Below is a list of questions/things-that-should-be-fixed that I found.

* What exacty does the TODO comment for ‘ghc-hsyaml’ mean?  The
  ‘native-inputs’ comment should also be removed if tests aren’t
  enabled.  This applies to ‘ghc-stmonadtrans’ as well

* The ‘inputs’ comments for ‘ghc-silently’ should probably be removed.

I noticed that a lot of new packages have been auto-generated and added
as-is, without checking licenses and fixing descriptions.  I have
attached a patch that fixes these (I hope I didn’t miss any packages).
