+ * partoken-102.ch (max_command): split off @d since different for pTeX.

+% $Id$
+% Implementation of |\partokenname| and |\partokencontext| primitives.
+% Public domain. Originally written by Petr Olsak, 2021.
+
+% TeX inserts (let's say) "par-token" at empty lines and in other situations.
+% The primitive meaning of "par-token" is (let's say) "end-paragraph",
+% but it can be changed by the macro programmer (by |\def\par|, for example).
+% The name of the auto-emitted "par-token" is fixed as |\par| in
+% classical TeX.
+% The new |\partokenname| primitive defined here allows changing this cs name.
+% After |\partokenname <control-sequence>| is given, the specified
+% <control-sequence> will be emitted at empty lines, etc., not |\par|.
+% Moreover, the given <control-sequence> plays the role of |\par| when
+% processing not-\long macros ("runaway error").
+% The setting of |\partokenname| is global.
+%
+% The integer register |\partokencontext| allows controlling the places where
+% "par-token" is auto-emitted. The value of |\partokencontext| can be:
+% 0 ... "par-token" is emitted as in classical TeX, i.e. at empty lines,
+% before \end, \vskip, \hrule, \unvbox, and \halign (if horizontal mode
+% is current) and in several error recovery situations.
+% This is the default value.
+% 1 ... "par-token" is emitted as before and at the end of \vbox,
+% \vtop, and \vcenter if horizontal mode is current here.
+% 2 ... "par-token" is emitted as before and at the end of \noalign,
+% \vadjust, \output, \insert, and \valign items, if horizontal
+% mode is current here.
+% Classical TeX does a direct call of the "end-paragraph" routine at the
+% places mentioned in cases 1 and 2.
+%
+% See the user documentation in the pdftex manual for more,
+% the tests/partoken-test.tex file for basic examples,
+% and the OpTeX format (eventually) for the practical case inspiring
+% this idea.
