[R] slanted ends of horizontal lines for certain line widths

if I plot a horizontal line, e.g.,




then the left end (1st example) or both ends (2nd example) of the lines
are not rectangular but slanted on the graphical display (screen).
That behavour first occurred when I was trying to plot a stepfun, e.g.,

y <- round(rnorm(12),1)
Fn12 <- ecdf(y)
plot(Fn12,verticals= FALSE, do.p = FALSE,lwd=2,col.h="red")
plot(Fn12,verticals= FALSE, do.p = FALSE,lwd=4,col.h="red")

(lwd=3 seems okay)

Bug or feature?
Suggestions? (I don't like the slanted ends but lwd=2 would be better
than lwd=3)
