 Fix #line pragmas in nested comments

 When parsing a nested comment or nested doc comment in the lexer, if we
 see a line starting with '#' we attempt to parse a #line pragma. This
 fixes how ghc handles output of the C preproccesor (-cpp flag) when the
 original source has C comments or pragmas inside haskell comments.

 Updates haddock submodule.
