Shouldn't the \relax stop it scanning ahead anyway?
but in the boxed case the } stops the scan but it seems
having decided that test is not a keyword it is inserting a space
before it which seems wrong. More surprising is that it eats ! here even
though ! isn't part of the allowed syntax as far as I can see
\def\imga{\hbox{\XeTeXpdffile "image.pdf"\relax!}}

The effect on linebreaking is more or less accidental "test" can't be
hyphenated so it's not surprising that some lines can not be justified,
and the extra space or not space after the image is changing the
linebreaking in the paragraph.

and then process with "xetex test.tex" on the command line, then the

after the image is too long and goes into the margin. You can see this
in the attached file.
I found wrapping the \XeTeXpdffile in an \hbox, thus:
\def\img{\hbox{\XeTeXpdffile "image.pdf"\relax}}
fixed the problem, but I don't see why this should be necessary.
Is this a bug?
XeTeX reports its version as follows:
$ xetex test.texi
This is XeTeX, Version 3.14159265-2.6-0.99998 (TeX Live 2017/Debian)
