IO::Handle.lines expressed as .get
IO::Handle.lines expressed as .get

This simplifies IO::Handle.lines to use .get and not do any smart
bypasses anymore.  Also no longer update .ins and make .ins DEPRECATED.
This makes .lines in its various forms about 60% slower, but it paves
the way for other features, such as supporting regexes as newline
separators.
