Hi

?lines says

      For 'type = "h"', 'col' can be a vector and will be recycled as
      needed.


Why doesn't lines() recycle colours for other types?

If I type

> plot(0:1,0:1,type="n")
> lines(runif(11),runif(11),col=c("red","green"))
>

then all ten lines are red, with no warning given. Is there a reason why
colour recycling would be a bad idea in this case?   Also, it would be nice if arguments such as lwd were recycled if needed too.
