  * deals with special shortURI cases. These special cases are the "smb:"
  * URL scheme which is very specific to KDE, "#" and "##" which are
  * shortcuts for man:/ and info:/ protocols respectively. It then handles
  * local files.  Then it checks to see if the URL is valid and one that is
  * supported by KDE's IO system.  If all the above checks fails, it simply
  * lookups the URL in the user-defined list and returns without filtering
  * if it is not found. TODO: the user-defined table is currently only manually
  * hackable and is missing a config dialog.
