[luatex] finish_pdffile callback

[Br. Samuel Springuel]

I noticed in the docs that LuaTeX has a `finish_pdffile` callback whose 
short description is "Called when all pages have been written to the PDF 
file."  Does this mean that LuaTeX has closed the pdf file when this 
callback is executed (and thus it is safe for the callback to instruct 
other tools to manipulate the pdf file)?
