Normally, no quoting is necessary in this case (other than required by the shell
to make it a single argument).

Ok, got it. The discrepancy comes not from the version of the engine but from
the underlying distribution: Debian (even sid) still ships TeX Live 2009. The
(partially-working) autoquoting mechanism was introduced in the lualatex format
in TeX Live 2010.

This was not the intended use, so the lualatex format adds an extra pair of
quotes, which is obviously wrong.

I would have expected pdflatex to fail in the same way in this case, but it does
handle is correctly, and so does xelatex (but with a slightly different
implementation).

Yep, this was the intended use. It works with pdflatex and xelatex too.

Yep, this was the original problem that started the whole story. I fails in the
same way with the more usual invocation

        lualatex luatex\ test.tex

and the change in the lualatex format in TL 2010, introducing autoquoting of the
job name, was meant to fix this problem. (We noticed only too late that the fix
didn't work with the less usual invocation style used by AucTeX.)

Yep, this may be called manually quoting the job name, as opposed to the
(imperfect) autoquiting feature of the lualatex format in TL 2010.

This is equivalent to

        lualatex luatex\ test.tex

which, as mentioned above, was the original problematic case in TL 09.

Unfortunately not, and I'm really sorry for that. I tend to recommend the

        --jobname=luatex\ test

way, since it works for TL 2010 and TL 2011, and this is more important IMO than
supporting 2009 even if it is the Debian version for the following reasons:
1. Debian users seem unlikely to use spaces in their tex filenames too often, I
believe this is rather an habit of Windows and OS X users;
2. LuaTeX users tend to want up-to-date suff anyway.
(I admit this reasons are rather based on clichés.)

The only good news in this picture is that, however you quote the argument of
--jobname, it will work with any version of TeX Live if the filename doesn't
contain spaces. So it is probably still a good idea to add --jobname: it would
fix the problem with the autoquote fix in TL 2010/11 for filenames without 
spaces.

Manuel.

PS: I confirm your current syntax works with LuaTeX 0.71 on top of TeX Live
2011, as will the --jobname luatext\ test syntax. I'll also arrange for the
--jobname \"luatex\ test\" to work now that I'm aware of the issue.
