[Rd] problem in plot(), combining log="y" with type="s" (PR#1078)

[Setzer.Woodrow@epamail.epa.gov]

I just noticed this behavior of plot().  If you combine: log="y", with type
="s", specify ylim, AND have plotting points outside of ylim, then the R
process hangs.
For example:

plot(1:10,seq(0.0001,1,length=10),ylim=c(0.01,1),type="s",log="y")

It will also hang if the original plot() command did not specify ylim, but
a subsequent
lines(x,y,type="s")
has data points outside the plotting limits established by plot.

In Windows 98, [Esc] does not interrupt the loop, but in Irix, ^C does.

I've found this in both:
