Research direction
Start at the tail command entry point and inspect the handling of non-seekable input, stream mode, and -f. Compare the related issue #11491 before choosing the implementation path. Done means tail -c +N can use splice() to send non-seekable input to /dev/null, including the stream and -f cases.
