Update to 2.39

Changelog:
Changes in version 2.39
-----------------------

* Fix unneccessary warnings when @ARGV contains undefs (yes, it
  happens).

* Passing an object as first argument to the callback handler for <>
  turned out to be a problem in cases where the argument was passed to
  other modules, e.g., Archive::Tar. Revert the change since the added
  functionality of the object is not really relevant for the <>
  callback function.

* Silence the deprecation warnings from newgetopt.pl for the purpose
  of testing. These tests will be removed along with newgetopt.pl in
  the next major release of perl.
