SF.net SVN: docutils:[9769 ] trunk/docutils

Revision: 9769
          http://sourceforge.net/p/docutils/code/9769
Author:   milde
Date:     2024-06-18 07:44:41 +0000 (Tue, 18 Jun 2024)
Log Message:
-----------
Deprecate "parser_name" argument of `readers.Reader.__init__()`.

Instead, the "parser" argument accepts now a parser name as well as
a `parsers.Parser` instance.

Also change some boolean values from `1` to `True`.
