Allow anything to follow a closing brace at start of line

Specifically this fixes an indentation issue with this:

    if ($host = example.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

Before this change this would have been indented as:

    if ($host = example.com) {
        return 301 https://$host$request_uri;
        } # managed by Certbot

Because the regular expression was looking for a ‘}’ with nothing following it,
but comments can follow this construct just fine.
