I am in complete agreement with Neil on this point. The addition of the
leading CRLF was made for good reason. I am embarassed to say that I didn't
implement this correctly in one case in my code, but I have subsequently
fixed that.
As for whether or not a dot is allowed in a tspecial, I have no strong
feeling about it. I implemented a very lenient parser that does not care
about this particular detail. And thus far I haven't had the need to generate
any parameter values containing a dot that didn't need quoting for other
reasons.
