[Rd] Unexpected difference in Bounding Box of PDF graphics between (PR#9072)

[Prof Brian Ripley]

Please take great care not to start a new bug report when commenting on an 
old one, as you have done here.  It really makes a mess of the records on 
the repository.  (Ensure that the PR# item appears on the first line.)

We do suggest quite strongly that people do not send reports on 
R-devel to R-bugs, as it is often `under development' as here.  If you 
want to comment on R-devel, do make sure you are using the 
up-to-the-minute version, and use the R-devel list.
