# [Bioc-devel] Section~\ref{sec:bla} idiom in vignettes

Hi,

In LaTeX, I like to use the tilde in connection with equation or section references, e.g. "Equation~(\ref{eq:bla})" or "Section~\ref{sec:blo}", to make sure they are not separated by a line break.

This has worked well for two decades and still does on my system. However, in some vignettes coming from the devel branch of the build server e.g. http://bioconductor.org/packages/devel/bioc/vignettes/DESeq/inst/doc/DESeq.pdf this is now rendered with a visible "~", which looks ugly.

Interestingly, the release version http://bioconductor.org/packages/2.11/bioc/vignettes/DESeq/inst/doc/DESeq.pdf does not render the tilde.

This was today 3 Feb, 12:20h CET. I wonder what causes this, and who/what can restore the intended behaviour.

Best wishes
Wolfgang
