Trying to debug (after update to sphinx 1.8.5 from 1.7) documentation biulding produced by sphinx, we see in generated LaTeX files calls to
with an argument involving a path to a file, like
baz is the actual citation label.
What should this mean? I have never seen such references in my 25+ years working with LaTeX.
Indeed, we have
thebibliography in the file
../foo/bar.tex, but is it supposed to work? Or this is a bug in the sphinx LaTeX support?
