[Rd] Update on "Shift-Return causes segfault (PR#3293)"

[Graeme.Ambler at bristol.ac.uk]

I've just rebuilt an rpm from the RedHat SRPM and the patches from ftp.gnu.org 
and R no longer crashes in any of the cases I have previously described.  I 
can let anyone who wants have a copy of the modified rpms for both RH8 and 
RH9.  The patch numbers are incremented one from the originals, so they 
should update cleanly on any system.

I guess you can probably close this bug now.  It's a bit annoying that RH 
didn't apply the patches themselves for RH9, since the relevant one came out 
about 6 months before RH9 was released!
