A block comment must affirmatively end before end of source

It wasn't clear to me that #1470 clearly resolved whether a block comment can be terminated by the end of source.

In that discussion I was against allowing that because it works against being able to easily glue together source texts.

I like this rationale. My previous weakly-held opinion was that this should fall under "don't generate errors that don't matter", but yours is a good enough reason for me to want to require strictness here.

• DN: Wasn’t clear in previous consensus. Requiring affirmative closing makes it more reliable/easy to glue together snippets.
• Merge

I just happened to see that C++14 has a similar requirement:

2.2 Phases of translation, paragraph 3 says

A source file shall not end in a partial preprocessing token or in a partial comment.12

with footnote 12 saying:

... A partial comment would arise from a source file ending with an unclosed /* comment.

So yay.
