docs: Normally hive.aux.jars.path is expanded from just being a path to the full
  list of files in the directory by the hive shell script. Since we normally
  won't be running from the script, it's up to us to do that work here. We
  use a heuristic that if there is no occurrence of ".jar" in the original,
  it needs expansion. Otherwise it's already been done for us.
  
  Also, surround the files with uri niceities.
