[Rd] strheight() crashes without opened device (PR#524)

[ligges@statistik.uni-dortmund.de]

My mistake, but also a bug.
I did not open a device and called strheight("X").
==> R crashed

...\rgui --vanilla
[...]

> strwidth("X")
Error in strwidth("X") : plot.new has not been called yet
(OK.)

> strheight("X")

R crashed.
(Happens also on Solaris.)
