Yes and no. These commands are simple enough that they do not need to
shut down gracefully, so they do neither handle nor ignore SIGPIPE, and
are thus instantly killed by it. That's why there is not error message.

That is because these commands are using printf without checking the
return value, which means that even if there is no more output, the
commands keep running until normal exit (or it's killed using e.g.
ctrl-c). We need to fix that. The status one is a bit harder to fix
because the print_status callback cannot not return an error.

I agree. The lack of an error return value in the print_status callback
is... sigh... yet another API problem.
