* lib/scanf.rb (Scanf::FormatSpecifier#letter, #width): use matched

  substring directly.

* ext/nkf/lib/kconv.rb (Kconv.conv): get rid of nil.to_a.

* test/ruby/test_assignment.rb, test/ruby/test_iterator.rb: followed
  change of sample/test.rb.

* test/net/http/test_http.rb: removed superfluous splatting stars.
