[Rd] bringToTop() when some windows been closed (PR#3512)

[Prof Brian Ripley]

We are talking about *devices* here, not windows and not figures.

Also, you are on Windows, where the device is called windows(), not
x11() (which is just there for back-compatibility).

The argument of bringToTop is a `device number'.  Unfortunately it tests 
this against NumDevices(), and that's not right.  The test has been 
corrected in R-devel.

As the FAQ says, please do not report guesses at the cause -- your
diagnosis is incorrect (and you have only one experimental point) and 
misled me.
