[luatex] Lualatex on windows with files inside "C:\Docume~1\"

[Michele Baresi]

Hi to all,

I'm trying to typeset music with Lilypond and Lualatex on Windows.
Lilypond-book creates a temporary tex file on a TMP repository belonging to
"C:\Docume~1" (aka Documents & Settings) and then lauches lualatex on it
... but it seems - to me - that lualatex doesn't like "~" in file names. It
gives me an error like this:

C:\Program Files\LilyPond\Test>lualatex
"C:\DOCUME~1\michib\LOCALS~1\Temp\tmpufl3v5.tex"
This is LuaTeX, Version beta-0.70.1-2011082320 (rev 4277)
 restricted \write18 enabled.
! I can't find file `C:/DOCUME'.
<to be read again>
                   \protect
<*> C:/DOCUME~
              1/michib/LOCALS~1/Temp/tmpufl3v5.tex
Please type another input file name:

Any ideas?

Thanks,
Michele
