Fixed a split_like_shell() bug introduced in 0.2603 for Windows, in
which an array reference passed as an argument was returned as an
array reference, rather than as a list. [Spotted by Steve Hay]module_name() will now return '' instead of undef when module_name
is not set. This eliminates a couple uninitialized-value
warnings. [Suggested by Michael Schwern]The expand_test_dir() method will now skip dotfiles (like ._foo.t,
which sometimes gets automatically created on Mac systems) when
'recursive_test_files' is in effect. [Tom Insam]
