filetype is set correctly (since we get `ruby....` options), but something weird is happening even with 2html.vim. Here is a minimal example:

```test.rb
# Ruby program listing
def foobar
   print("Hello World")
end
```

Run:

vim -u NONE -c "syntax manual" -c "set syntax=ruby" -c "source /usr/share/nvim/runtime/syntax/2html.vim" -c "wqa" test.rb

gives

```test.rb.html
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
...
</head>
<body>
<pre id='vimCodeElement'>
# Ruby program listing
def foobar
 print(&quot;Hello World&quot;)
end

</pre>
</body>
</html>
<!-- vim: set foldmethod=manual : -->
```

which is similar to what 2context.vim gets. If I source tohtml.vim or 2context.vim from an existing vim session, then the tags are correct. I have not been able to figure out why this is happening.
