[XeTeX] Problem with XeTeX's (and perhaps other binaries -- not investigated) handling of --output-directory

[Philip Taylor]

If XeTeX is invoked on file foo.tex specifying --output-directory=../dynamic-content,
and if there is also a file ../dynamic-content/foo.tex, then XeTeX will process that file
rather than the file which it was instructed to process :

> \message {This is the intended foo.tex}
> \end


> This is XeTeX, Version 3.14159265-2.6-0.99996 (TeX Live 2016/W32TeX) (preloaded format=xetex)
>  restricted \write18 enabled.
> entering extended mode
> (../dynamic-content/./foo.tex This is the unintended foo.tex )
> No pages of output.
> Transcript written on ../dynamic-content/foo.log.
