The aim of the secure viewer then was to make difficult to obtain eyes-only
message text as a file or a pipe. It checked if output is a live tty,
prevented the plaintext ending on the swap and leaving any temp files.
It was really difficult to get eyes-only message in plain file form with it
in the way (there was no /dev/vcs etc in the days and it needs root anyway).
