   The intention here is to block STDOUT because redirecting raw output of STDOUT   
   from an archive utility was something I considered a security risk.  It will   
   likely expose all of the directory structure of your system which makes it   
   easier to exploit (if one were to exist).   
      
   The external view command is intended to populate the archive data into the   
   temporary display file and then Mystic displays that file.  How that data gets   
   into the file is not up to Mystic, its up to whatever program the view command   
   executes. That is the desired implementation of external viewer support.   
      
   (There is also an unfinished scripted view extension that works with the ANSI   
   viewer to allow external archivers to use the full ANSI viewer functionality.   
   I need to get that done one of these days)   
      
   I could change it in Linux to only suppress STDERR just for view but then when   
   someone does set up an archive viewer in the intended way, Mystic is going to   
   show its output (by default) which would be undesired and potentially   
   unsecure.    
   Mystic is trying to err on th side of security but it still allows you to do   
   both a direct redirection like you are doing too - it just defaults to being   
   conservative in this situation and makes you work a little more to do a STDOUT   
   redirect.
