Interesting, the opposite feels completely unnatural to me: The comment
only applies if the condition is true, whereas in the case I was quoting,
it looks like it applies no matter what.

Regarding the extra curly braces, I think it's OK to leave them out,
like so:

    if ([...])
      /* This is a comment that ...  */
      return;

If we prefer keeping the comment before the condition, then I would
suggest we rewrite the comment to say so.  Something like this:

    /* If this is an old thread, or there is something else
       special to it, then it's ok to do nothing.  */
    if ([...])
      return;
