+ * Returns the name of the display XOpenDisplay would use.  This is better
+ * than just printing the "display" variable in a program because that
+ * could be NULL and/or there could be an environment variable set.
+ * This makes it easier for programmers to provide meaningful error
+ * messages.
+ *
+ *
+ * For example, this is used in XOpenDisplay() as
+ *	strncpy( displaybuf, XDisplayName( display ), sizeof(displaybuf) );
+ *      if ( *displaybuf == '\0' ) return( NULL );
+ *  This check is actually unnecessary because the next thing is an index()
+ *  call looking for a ':' which will fail and we'll return(NULL).
