* lib/yaml/rubytypes.rb: remove comments that are bungling up

  the rdoc and ri output.  output symbols as plain scalars.

* ext/syck/rubyext.c (syck_emitter_reset): emit headless
  documents always.

* ext/syck/emitter.c (syck_scan_scalar): quote scalars with any
  kind of surrounding line space, tabs or spaces alike.

* ext/syck/token.c: accept tabs as whitespace, not for indentation,
  but strip from plain scalars.

* test/yaml/test_yaml.rb: remove outdated tests.
