Revision: 10017
http://sourceforge.net/p/docutils/code/10017
Author: milde
Date: 2025-03-06 08:41:10 +0000 (Thu, 06 Mar 2025)
Log Message:
-----------
Fix LaTeX docinfo handling of affiliation fields preceding author field.
With "use_latex_docinfo", the content of the bibliographic fields
"address", "contact", and "organization" is attached to the author name.
Reserve the first position for the author name instead of creating an
"author info" list without author if any of these fields appeares before
an "author" or "authors" field.
