Subject: [PATCH] tools: avoid generating duplicate id attributes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In all.html, we currently generate hundreds of duplicate id attributes
because of conflicts between the way allhtml.mjs prefixes in-page links
with the module name on the one hand, and the existence of legacy id
attributes hardcoded into the page on the other hand.

This prefaces the module name with `all_` to avoid the conflicts.
