[luatex] [MiKTeX] Calling texlua from texlua, with a space in the tex binary path

[Akira Kakuto]

Dear Siep Kroonenberg,

> By the way, why 'test' in kpse.set_program_name?

In my previous example, the program name was irrelevant.
kpse.set_program_name() was used only to initialize kpse.
If program name is necessary, it should be the real program name.

Thanks,
Akira
