(HP-UX) scan: last line gets duplicated (PR#790)

The last line gets duplicated when a file is read like this:

    a <- scan(file=filename, what="", sep="\n",
                    strip.white=c(TRUE), quiet=TRUE)

Version:
 platform = hppa2.0-hp-hpux10.20

 major = 1
 minor = 2.0
 year = 2000
 month = 12

This bug PR#672, also reported from your institution.

That would be me. I reported this bug before, for R version
1.1.0

It has only been reported from HP-UX, and only from your
systems. Could someone there debug it, please?

I would fix it, if I new how to. Perhaps you can suggest
something from the warning messages I get.

During compiling I get a lot of warning messages. These are for
scan.c:

I get these type of warnings when compiling other sources too:
	sock.c
	sys-std.c
	connections.c
	g_alab_her.c
	../../../R/src/main/gram.y
	iosupport.c
	main.c

	saveload.c
