[Rd] Problem with sink() in 1.20 on Windows (PR#779)

[Setzer.Woodrow@epamail.epa.gov]

When I use sink(filename) to save the results of the run, the file
does not seem to be closed or released back to the OS after I issue
the "sink()" command.  Here is a baby example:

sink("test.txt")
tdta <- data.frame(x = x <- 0:10,y = 2 * x + rnorm(11))

print(summary(lm(y ~ x, data=tdta)))
sink()

At this point (even after refreshing the Explorer window) the filesize of
"test.txt" is listed as 0 bytes, and as long as Rgui is running, I
cannot delete the file.  Emacs cannot read the file (but Notepad can).  This happens both in the gui
and when the commands are in a file run via "source()".
