    Give proper argument to `TeX-command-expand'
    
    * preview.el.in (TeX-inline-preview-internal): Give `TeX-region-file'
    or `TeX-master-file' as `file' argument of `TeX-command-expand' when
    preamble caching is enabled.  This argument used to be nil, which
    caused error when lualatex is in use.  The fourth element of the
    `luatex' entry of `TeX-engine-alist-builtin' contains "%s", which
    eventually triggers the use of the `file' argument.
