R scripting patches for R-1.7.0

I've patched R so that it can be used as a scripting language, i.e.
you can (on Unix-like systems) write files containing R code
and execute them non-interactively, e.g.:

	#!/usr/local/lib/R/bin/R.bin --script

	cat("Hello World!\n")

I've updated the patches for R-1.7.0; if you're interested in the
patches, e-mail me at mckay@gmr.com, and I'll send them to you.
