Subject: * ext/syck/emitter.c (syck_scan_scalar): prevent indicators from  
 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.
