.Rbuildignore does not skip the gh-pages book chapters from CRAN

[vincentvanhees]

We do not want these chapters on CRAN as they are intended to be like a book style long narrative text.

Action needed:

Replace
^vignettes/chapter*.Rmd
by
^vignettes/chapter.*\\.Rmd$

Re-opening this issue, because it seems not fixed yet. Somehow the trick above did not work as CRAN still shows the chapters https://cran.r-project.org/web/packages/GGIR/index.html.
