From c5510d684e4879ab9a5295b4a1981888a4268627 Mon Sep 17 00:00:00 2001
From: Robin Haberkorn <robin.haberkorn@googlemail.com>
Date: Sun, 3 Aug 2025 17:56:04 +0300
Subject: simplified the htbl.tes preprocessor and the SUBST_MACRO using new
 --quiet, --stdin and --stdout options

* htbl.tes now reads from stdin and writes to stdout.
  Allows avoiding temporary `*.htbl` files
* grosciteco.tes still cannot be simplified since --stdin cannot be combined with
  passing command-line arguments (FIXME).
