[Rd] (PR#11537) help (using ?) does not handle trailing whitespace

[Tim Hesterberg]

By whitespace, I mean either a space or tab (preceding the newline).

I'm using ESS:
ess-version's value is "5.3.6"
GNU Emacs 21.4.1 (i486-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of
2007-08-28 on terranova, modified by Debian

I have the following in my .emacs:
(load "ess-5.3.6/lisp/ess-site")
(setq ess-tab-always-indent nil)
(setq ess-fancy-comments nil)

I have not edited ess-site.el
