That's because the interrupt signal is not caught.
This works:
sh -c 'echo foo >"$1" && trap "exit 1" INT && sleep 20' test hoi || rm hoi
And so does this:
#!/bin/sh
ruby - hoi <<EOF || rm hoi
File.write(ARGV[0], 'foo')
begin
sleep(10)
rescue Exception
exit(1)
end
EOF
Both asciidoc and asciidoctor trap the signal.

Yes, if we agree this approach is indeed desirable I can do that.
