Well, issuing an ERROR on the stable branches would be troublesome for
extension developers when reloading after a minor update if they did
not set their short_desc in a custom GUC.  So, while I'd like to
encourage the use of short_desc, using your suggestion to make the
code more flexible with NULL is fine by me.  GetConfigOptionByNum()
does that for long_desc by the way, meaning that we also have a
problem there on a build with --enable-nls for short_desc, no?
