In my understanding, a line contains some characters (possibly no
characters) and then an end of line indicator.  By this reading,
"<CRLF>.<CRLF>" is *two* lines: an empty line and a line containing
only a dot.

The dot-stuffing algorithm talks about lines in this way: some
characters (or octets) followed by an EOL indicator.

In "DATA<CRLF>foo<CRLF>.<CRLF>", does the message contain "foo" or
"foo<CRLF>"?  Or even "<CRLF>foo<CRLF>"?
