Not reparsing when EOF inside comment

In case reparsing upon EOF inside comment is considered:

Reparsing anything upon EOF is bad for security, because stuff that a  
gatekeeper thought was harmless can turn into a runnable script if an  
attacker manages to force a premature EOF e.g. by disrupting the  
network stream.

If the spec ends up specifying reparsing anyway, rewinding the byte  
stream to a particular point is more painful from an implementation  
perspective than simulating document.write with the decoded characters  
accumulated in the comment buffer.
