export lists should not count as examples

[gelisam]

e.g. at https://exhack.org/packages/Earley/Text-Earley-Parser, all the examples found currently point to a line inside the following export block, which isn't very illuminating:

module Text.Earley
  ( -- * Context-free grammars
    Prod, terminal, (<?>), Grammar, rule
  , -- * Derived operators
    satisfy, token, namedToken, list, listLike
  , -- * Deprecated operators
    symbol, namedSymbol, word
  , -- * Parsing
    Report(..), Parser.Result(..), Parser, parser, allParses, fullParses
  , -- * Recognition
    report
  , -- * Language generation
    Generator, generator, language, upTo, exactly
  )
