Subject: Fix indentation of closing braces

The ‘nginx-indent-block’ function would get confused by braces in comments. Here
is an example of how indentation could go wrong:

    server {
        # some comment with {
        # ...
        }

After this change the example is correctly indented:

    server {
        # some comment with {
        # ...
    }
