Summary: markupbase parse_declaration cannot recognize comments

Initial Comment:

In markupbase class parser method parse_declaration

It verfies that the first two characters are "<!"

Then it returns -1 if the next character is "-".

After that, it checks to see if the next two characters 
are "--", but if they were, it would already have returned.

Solution:  Check for comments before checking for a 
short buffer.

        if rawdata[j:j+1] == '--': #comment
            # Locate --.*-- as the body of the comment
            return self.parse_comment(i)
        if rawdata[j:j+1] in ("-", ""):
            # Start of comment followed by buffer 
            # boundary, or just a buffer boundary.
            return -1
