Unfortunately, this is wrong. Consider these examples:

  if (x) f(); // here it will work
  if (x) f() /* here it won't */ ;
  do if(y) {}while (x); // and here too

I don't know if the AST provides a convenient way to find out if there's a 
semicolon behind the end of the statement and where it is located. I also don't 
know why the statements that end with a semicolon do not store its location or 
just include it in the source range. We need to ask someone more familiar with 
the AST.

It's fine here, as there's not much you can do. I was only talking about 
removing extra dashes from the file header comments.
