Fix some NSEDoc. Some libraries had @copyright and @author right at the

top of the first comment, so the entire description got stuffed into the
@author field. I also discovered a limitation in the NSEDoc parser: the
first non-empty line following the first --- comment must be the
"module" call, or else the block isn't recognized as belonging to a
module. This was preventing @args from appearing in certain libraries.
Djalal Harouni told me about this.
