-% Quote \jobname if it contains spaces, similarly to what pdfTeX does.
+% Quote \jobname if it contains spaces, similarly to what other engines do.
%
% Recent versions of luatex kindly provide a process_jobname callback for
% this. Detect if it is available and use a fallback in pure TeX otherwise.
% If using the callback, register it at \everyjob time since callbacks are not
% dumped in formats currently.
%
-% The TeX version fails with "luatex '\input foo'" invocations, but it can
-% either support that or spaces in filenames, not both. This one is kept for
-% historical reasons.
+% The TeX version fails (jobname is set to texput) with invocations like
+% luatex '\input foo'
+% but work correctly with the following:
+% luatex foo\ bar
+% luatex -jobname foo\ bar '\input "foo bar"'
+% It is is not possible to support all this case without the callback. It is
+% debatable if supporting another set cases would be better, but this is the
+% historical (TL 2010) behaviour, so just keep it.
+%
+% \jobname quoting is normalized in the same way as in web2c's
+% normalize_quotes() function (see lib/texmfmp.c, non-XeTeX case), that is:
+% - remove quotes
+% - complain if quotes are not "balanced" (ie not in even number)
+% - enclose the result in quotes iff it contains spaces

% This file is inputed after latex.ltx.
