Ok, so if a comment only starts with '<!' then it ends at the first '>'
only (ignoring any '--'), but if a comment starts with '<!--' then it
must end with '-->'.

Ok.

I was working on the assumption that the comment would end at the first
occurance of '>' while in the comment end state, but that whitespace
would be ignored while searching for it. Several browsers already
handle it like that including Mozilla, Opera and Safari (except in
Opera, the comment contained " > FAIL -"). Although IE, OmniWeb and
iCab failed.
