[Erlyaws-list] [PATCH] Fix \ifpdf when pdflatex is creating DVI

[Hans U. N. <hu...@n-...>]

Modern LaTex distributions use PDFLaTeX to create DVI files.

So we cannot just check whether we are using PDFLaTeX, but
also whether the output format is DVI or PDF, in order to
set up the \ifpdf conditionals.
