Old description:

 A language pragma like

 {-# LANGUAGE
 TypeOperators,
 FlexibleContexts #-}

 parses just fine but

 {-# LANGUAGE
 TypeOperators,
 FlexibleContexts
 #-}

 doesn't, saying:

 Cannot parse LANGUAGE pragma
 Expecting comma-separated list of language options,
 each starting with a capital letter

 An OPTIONS pragma, on the other hand, accepts either format without
 complaint.

Comment(by daniel.is.fischer):

 The user's guide says
 {{{
 The layout rule applies in pragmas, so the closing #-} should start in a
 column to the right of the opening {-#.
 }}}
 The language report doesn't mention any such restrictions though, so
 perhaps it should be listed in Bugs and infelicities (supposing the parse
 can't easily be changed to accept the `#-}` anywhere).
