If you read further back in the thread, the list administrativa emails
don't use customheaders at all, which means adding the listtext macros
benefits all of those mails.

By way of macros, it would be really helpful if we could get per-header
reading from a custom file in control.

==
%ifhasheader CONTROLFILE HEADER%
%getheader CONTROLFILE HEADER%
%else%
HEADER: DEFAULTVALUE
%endif
==
This would check in control/CONTROLFILE for one or more header lines
starting with "HEADER:", and copy them in if they exist.
If they do NOT exist, it would emit "HEADER: DEFAULTVALUE".

This could be used for still being able to override single headers,
while keeping macro-based listtexts.

Would be really useful in customheaders as well, for those of us that
run many lists.

In the Gentoo case, I'd want to override List-Archive, List-Subscribe,
List-Unsubscribe, List-Id (I omitted it in the patch above, as for
legacy threading, our list-id no longer matches the $list$.$domain$,
domain has changed slightly).
