Tabs inside scalars

Hi!

I have example output from Ruby 1.8 that fails to parse with SnakeYAML:

"36L\tDIESEL" dumped from Ruby 1.8 gives "--- 36L\tDIESEL\n"

When loaded with SnakeYAML it throws an exception:

Exception in thread "main" while scanning for the next token
found character 	'\t' that cannot start any token
 in "<string>", line 1, column 8:
    --- 36L	DIESEL
           ^

This is currently being tracked at http://code.google.com/p/snakeyaml/issues/detail?id=136

The question is wether the example is legal YAML.

I have read the specs, and I find them inconclusive.  Ruby 1.8 has been around for a long while, and the use of YAML with Ruby is widespread, being in the standard library and all.  So I assumed that the output is legal YAML and that SnakeYAML should accept it.

Anybody got an answer on this?
