 Test Script:
 {{{
 #!ruby
 $ cat test.rb
 p File.basename("..")
 p File.basename("..", "test")
 p File.basename("..", "*")
 p File.basename("..", ".*")
 }}}

 Result of Ruby 1.9.1:
 {{{
 $ ruby test.rb
 ".."
 ".."
 ".."
 ".."
 }}}

 Result of MacRuby Trunk:
 {{{
 $ macruby test.rb
 ".."
 ".."
 ".."
 "."
 }}}

 It seems that Implementation of the rmext() is not enough.[[BR]]
 Merged from Ruby 1.9:
