[tex-live] grffile wrong behaviour on OS X 10.11.3 with MacTeX 2015

[Sören Vogel]

Hello

I have found a wrong behaviour of grffile (oberdiek) with lualatex (MacTeX 2015) on OS X 10.11.3 (El Capitan).  The minimal example is:

`
\documentclass[a4paper, 10pt]{scrartcl}
\usepackage{luatextra}
\usepackage[british]{babel}
\usepackage[babel]{csquotes}
\usepackage{graphicx}
\usepackage[unicode, citecolor=blue, linkcolor=black, urlcolor=blue, colorlinks=true, bookmarksopen]{hyperref}%teal
\usepackage[multidot=true, babel=true, extendedchars=true, space=true]{grffile}
\begin{document}
\includegraphics[scale=.5]{Img here/My image.pdf}
\end{document}
`

Folder `Img here` contains file `My image.pdf` with a picture.  However, when trying to compile it with lualatex it complains:

`! Package pdftex.def Error: File `Img here/My image.pdf' not found.`

The example worked with MacTeX 2015 on OS X 10.10.X (Yosemite), and it also works with MacTeX 2014 on 10.11.3 (currently running the downgraded version).
