134	"Nested lists seems to be ""dumped"" incorrectly"	maksims.juvcenko@…	xi	"Problem occurs, when nested list is dumped. 


{{{
>>> s = {""a"": ['aaa','bbb','ccc']}
>>> print yaml.dump(s, default_flow_style=False)
a:
- aaa
- bbb
- ccc
}}}


According to specification of YAML 1.1 nested sequence items must have entry token equal to ""  -"" (two spaces and minus symbol), but in reality it lacks entry spaces.
This issue creates limitations, when YAML documents are passed between PyYAML and JYaml interpreters. 

Configuration:
 - PyYAML version: PyYAML 3.08
 - Python version: 2.5.2
