[whatwg] Ending comments with --!>

Internet Explorer 7, Firefox 3, Safari 3.1, and Opera 9.5 accept --!>
as an alternate comment terminator to the usual -->

In Internet Explorer 7 and Opera 9.5, if the document later contains
the usual comment terminator, then that character sequence terminates
the comment instead:

http://crypto.stanford.edu/~abarth/research/html5/comments/strange-ending-with-real-ending.html
http://crypto.stanford.edu/~abarth/research/html5/comments/strange-ending-with-later-comment.html

Firefox 3 and Safari 3.1 do not appear to exhibit this behavior.

(Interestingly, the syntax highlighter in vim suggests the document
will be parsed as in Firefox and Safari, no doubt contributing to
author confusion.)
