Subject: 1.8.0, YAML funny feature

hi
i happened to edit a yaml file manually. after doing so it didn t load 
anymore - parse error!
i think this should not happen. the parser /must/ become a bit more robust.

the problem: the parser handles "\n" and "\r\n" differently. a windos- 
specific problem?
See following irb session:

irb(main):006:0> YAML::load "-1\n-\n - 1\n - 2\n - 3\n-2"=> [1, [1, 2, 3], 
2]
irb(main):007:0> YAML::load "-1\r\n-\r\n - 1\r\n - 2\r\n - 3\r\n-2" 
ArgumentError: parse error on line 5, col 3: `-2'from 
F:/SCRIPT/ruby/lib/ruby/1.8/yaml.rb:28:in `load'
        from F:/SCRIPT/ruby/lib/ruby/1.8/yaml.rb:28:in `load'
        from (irb):7
irb(main):010:0> YAML::load "-1\r\n-\r\n - 1\r\n - 2\r\n - 3\r\n-2"=> 
["1\r", "\r-1\r - 2\r - 3\r", 2]

the last line loads (due to a space added at index 8) but is completely 
inacceptable.

annother question:
why does to_yaml print a space after a single - (dash)? ok - not against 
yaml syntax rules.
i have no real evidence yet,
but i believe that the parser relies on this in some special cases (as seen 
in the irb output).
