Quoting works if you use \XeTeXpicfile or \XeTeXpdffile directly.
However it doesn't work in \includegraphics (without package grffile),
because the space is also used as terminator in macro processing
of the file name.

In general the quoting feature can't be tested in a simple reliable
manner without trying file open. I assume that quoting is always
available in case of XeTeX. Because I couldn't find it documentated,
it might be luck if the assumption is right.
