removed the unlines-lines wrapper from Lexing.unlexer to prevent empty lines when an unlexer (such as -bind or -unchars) is used as an option in linearization. Don't know really why the input had been broken into lines in the first place. You can see the effect by importing LangEng and running "gr -cat=Cl | l -table -bind" before and after recompiling GF.
