219	A tab inside a scalar is not accepted	py4fun@…	xi	"I got the exception when a tab character (\t) is located inside a scalar:
{{{
import yaml

yaml.load(""36L\tDIESEL"")
}}}
This is the output of the latest source:
{{{
  File ""C:\projects\py-workspace\pyyaml-trunk\lib\yaml\parser.py"", line 143, in parse_implicit_document_start
    StreamEndToken):
  File ""C:\projects\py-workspace\pyyaml-trunk\lib\yaml\scanner.py"", line 116, in check_token
    self.fetch_more_tokens()

    % ch.encode('utf-8'), self.get_mark())

  in ""<string>"", line 1, column 4:

}}}
When the tab character is replaced with a space, the parser works properly.
