[Rd] ugly in plotmath: frac(1, sqrt(...)) (PR#1101)

[ligges@statistik.uni-dortmund.de]

Sometimes (dependent on device and settings of 'cex' and 'lwd') the line
of a square root symbol plottet in the denominator of a fraction appears
to be in or above the line of the fraction.

Examples:


### Choose one of these:
# pdf("test.pdf", height=6, width=8)
# bmp("test.bmp", width=1100, height=800, pointsize=12)
# bitmap("test.tif", type="tiff24nc", width=12, height=9, res=300,
pointsize=12)
# png("test.png", width=1100, height=800, pointsize=12)
# postscript("test.eps", height=6, width=8, horizontal=FALSE)

 par(cex=2, lwd=2)
 plot(1:10)
 text(2, 8, expression(frac(1, sigma[i]*sqrt(2*pi))))
dev.off()
