Christophe, I saw your post on r-devel. It really belongs there. We add nothing by discussing / hiding this in the Debian BTS.

No, we need to engage R Core to pick it up there. I do not like our R engine to differ from what you'd get elsewhere so I am *not* in favour of patches changing behaviour. Let;s change this upstream, and close it here.
