Trait ErrSpan

pub trait ErrSpan {
    type Result;

    // Required method
    fn err_span(self, span: Span) -> Self::Result;
}

An extension trait for Result, which adds a span to the error type.

This trait might be removed later, since the old Spanned<std::io::Error> to ShellError conversion was replaced by IoError.
