description:
Allow a new variable SUBST_FILTER_CMD.<class> that is a command filter or
pipeline that takes stdin, performs the substitions and writes the result
to stdout.  It defaults to ${SED} ${SUBST_SED.<class>}.  Use this variable
to replace the sed command with something else, like an awk process.
