Note that there are other changes in that version too:  stripchart() is 
a generic function, and it handles formulas more like boxplot() does 
than in 2.6.x or earlier.

In Windows if you start R with the --internet2 option (which uses IE 
APIs instead of regular networking) and Windows trusts the certificate 
authority, then https urls can be handled.  But svn.r-project.org is 
self-signed, so it doesn't help in this case.
