Unfortunately, this does not seem to work for me. Even though sed
stops reading after seeing the "### command list" line, I suspect
that its stdin buffer has been filled with other lines that follow
it from the input to the buffer size, consuming what you meant to
feed the later 'grep $matchgrp"' with.
This is a one-time thing, so I do not mind to update the Makefile
so that it does not feed command-list.txt from the standard input
but gives the path as "$1" to this script.
