[Automake-NG] [FYI 1/2] [ng] refactor: make '&verbatim' polymorphic in its return value

[Stefano Lattarini]

* automake.in (verbatim): If used in empty context, continue to act
as before, and append the read makefile fragment to '$output_verbatim'.
But if used in scalar or list context, return it instead.
