[Rd] (PR#11291) View functionhas problems going beyond 65536

[ripley at stats.ox.ac.uk]

This is specific to the scrollbar: paging/End work fine -- so the original 
subject list was seriously misleading.

It is a Windows limitation on scrollbars -- there was code to work around 
it, but it was not switched on  - will be in R-devel and R-patched 
shortly.
