I guess what I am not sure about is whether a final <CRLF> is always 
required in the SIMPLE c14n method.

If so, then the minimum is always l=2.

But consider when l > 2, does this still mean the ending 2 bytes for the 
L amount is <CRLF>?

What if the actual text is larger than L?

Example:

12345678<CRLF>
12345678<CRLF>
12345678<CRLF>
12345678<CRLF>
12345678<CRLF>
<CRLF>

here you have 52 bytes.  I believe canonicalized text size is l=50.

But what if the actual L= size defined in the DKIM-Signature: header is 
l=45? Is the canonicalized text then?

12345678<CRLF>
12345678<CRLF>
12345678<CRLF>
12345678<CRLF>
123<CRLF>
