I am afraid that there is nothing to be wikified... I opened it
(Mint 19.3/64b) in qpdfview and evince, print out by pdfinfo and mutool
and in all cases there is "a b c" or "a, b, c" (, = single left quote)
as was written. (My acroread is just broken and in xpdf and mupdf
I guess there is no service to display it.)
What is the reason that keyword attribute does not accept commas whereas
others (title, author...) do?
# keyword={{a, b, c}},
As far as I know, key words (in papers, books etc.) are used only as a comma
separated list of terms without further structuring so I cannot imagine
who and why would need braces in normal cases.
