3.5) Say something in the echo area when a viewer terminates with
output, so it doesn't interrupt the user if they're doing something,
but the output buffer is still discoverable. Maybe bind C-c ` to show
the most recently reported output buffer, like what (la)tex-mode and
others do, and mention this binding in the echo area message.

3.5.1) Don't create a buffer until the command has output (or, easier
to implement: create the buffer, but kill it on exit if there was no
output). When starting a new command, kill output buffers from
no-longer-running viewers that have never been visited (using
buffer-display-count or buffer-display-time).
