1689,Deprecate is_tty,NotFound,NotFound,"docs/book/pir/ch08_io.pod describe the isatty method of FileHandle and FileHandle implements it. StringHandle and GzipHandle, however have a method called is_tty that return 0. This isn't a very useful combination.

In r47784 I implemented isatty in Handle, returning 0. That way isatty can be used with an arbitrary Handle without knowledge of is exact type.

This leaves an unuseful is_tty method. I propose to deprecate it immediately.
