Shift back to previous character in the incoming bytes

Returns:boolean: false to indicate we are not in an EOS condition

skipWhitespace	back to summary
private boolean skipWhitespace() Consume initial whitespace and underscores so that next character examined is not whitespace. 1.9 and strict do not allow leading underscores. Returns whether next position is at the end of the string or not. Trivia: " _ _ _ _ 1".to_f == 1.0 in Ruby 1.8
