  appearing alone or at the end of plain scalars. [ruby-core:5826]

* ext/syck/emitter.c (syck_emit_scalar): treat typed scalar nodes
  as complex keys.

* lib/syck.h: version 0.60.

* lib/yaml/basenode.rb (YAML::BaseNode#at): transform keys during
  key searches.

* ext/syck/rubyext.c: loading of binary-typed nodes.  prevent
  emission of plain strings that look like symbols, but which aren't.

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* test/yaml/test_yaml.rb: remove outdated tests.

  emitter.

* lib/yaml/stream.rb: ditto.

* lib/yaml/rubytypes.rb: added Object#yaml_new.

* lib/yaml/tag.rb: the tag_subclasses? method now
  shows up in the class.  allow taguri to be set using an accessor.
  continue support of Object#to_yaml_type.

* ext/syck/rubyext.c: new emitter code.  yaml_new and yaml_initialize
  get called, should they be present.  consolidated all the diaspora of internal
  node types into the family below YAML::Syck::Node -- Map,
  Seq, Scalar -- all of whom are SyckNode structs pointing to
  Ruby data.  moved Object#yaml_new into the node_import and made it the
  default behavior.  the target_class is always called wih yaml_new, prepended
  a parameter, which is the klass.  loaded nodes through GenericResolver show their style.
  new Resolver#tagurize converts type ids to taguris.

* ext/syck/implicit.re: were 'y' and 'n' seriously omitted??

* ext/syck/emitter.c: renovated emitter, walks the tree in advance.
  consolidated redundant block_styles struct into
  the scalar_style struct.  (this means loaded nodes can now
  be sent back to emitter and preserve at least its very basic
  formatting.)

* ext/syck/gram.c: headless documents of any kind allowed.

* ext/syck/node.c: new syck_replace_str methods and syck_empty_*
  methods for rewriting node contents, while keeping the ID
  and other setup info.  added syck_seq_assign.

* ext/syck/syck.h: reflect block_styles and new node functions.

  problems for non-ascii characters. [ruby-core:03280]
* ext/syck/implicit.c: ditto.
* ext/syck/bytecode.c: ditto.

* lib/yaml/baseemitter.rb: folding now handles double-quoted strings,
  fixed problem with extra line feeds at end of folding, whitespace
  opening scalar blocks.

* lib/yaml/rubytypes.rb: subtelties in handling strings with
  non-printable characters and odd whitespace patterns.

* ext/syck/rubyext.c (yaml_org_handler): ditto.

* lib/token.c: indentation absolutely ignored when processing flow
  collections.  plain scalars are trimmed if indentation follows in
  an ambiguous flow collection.

* lib/yaml/rubytypes.rb: exceptions were using an older
  YAML.object_maker. [ruby-core:03080]

* ext/syck/token.c (sycklex_yaml_utf8): using newline_len to
  handline CR-LFs.  "\000" was showing up on folded blocks which
  stopped at EOF.

* ext/syck/token.c: re2c compiled with bit vectors now.
* ext/syck/implicit.c: ditto.
* ext/syck/bytecode.c: ditto.

  thanks, ts. [ruby-core:02931]

* ext/syck/token.c (sycklex_yaml_utf8): buffer underflow.
  thanks, ts. [ruby-core:02929]

* lib/yaml/baseemitter.rb (indent_text): simpler flow block code.

* lib/yaml.rb: added rdoc to beginning of lib.

* lib/yaml/baseemitter.rb (indent_text): was forcing a mod value
  of zero at times, which kept some blocks from getting indentation.

* lib/yaml/baseemitter.rb (node_text): rewriting folded scalars.

* ext/syck/syck.h: reports style of scalars now, be they plain, block
  single-, or double-quoted.

* ext/syck/syck.c: ditto.

* ext/syck/gram.c: ditto.

* ext/syck/node.c: ditto.

* ext/syck/token.c: ditto.

* ext/syck/rubyext.c (yaml_org_handler): symbols loaded only
  if scalar style is plain.

* ext/syck/rubyext.c (yaml_org_handler): some empty strings were
  loaded as symbols.

* test/yaml/test_yaml.rb (test_perl_regexp): updated test to
  match new regexp serialization.

  for Ranges, Strings, Structs, Regexps.

* lib/yaml/rubytypes.rb (to_yaml_fold): new method for setting a
  String's flow style.

* lib/yaml.rb (YAML::object_maker): now uses Object.allocate.

* ext/syck/gram.c: fixed transfer methods on structs, broke it
  last commit.
