But the quoted string may contain virtually ANY character, no?

Legal:
89ab;value\r\n
89ab;key=value\r\n
89ab;key=\"value\"\r\n
89ab;key=\"line1\r\nline2\rline3\nline4\"\r\n

Illegal:
89ab;key=line1\rline2\r\n
89ab;key=line1\r\nline2\r\n

Since we ignore everything after the ; anyway, I don't want to parse 
this, really. But we run into serious problems in the case where a \r\n 
occurs within the quoted string!
I have never encountered a server using this in the real-world (but I 
haven't seen enough servers). So once again: Has anybody ever see a 
server using this?
