I agree that filters are a VERY good unix behavior, they're very script 
friendly.

However, we can make them much more human-friendly if we look if stdin 
is a TTY and emit a nice message. If the program is used as a filter, 
then stdin is not bound to a TTY. The case that someone types in text 
directly into GnuPG is very, very rare.


For example, if you confuse "mailstats" (from sendmail) with "mailstat" 
(from procmail) and type as a command, the following will happen:

  $ mailstat
  Most people don't type their own logfiles;  but, what do I care?
  $

However, "cat logfile | mailstat" or "mailstat <logfile" or whatever 
works as expected. So we have both: script-friendlyness and 
human-friendlyness.
