Hi not sure as I do not know actual syntax, but seems to me that in type=h there segments are drawn from x axis to x,y values, hence the recycling behaviour has some sense.
In other types I wonder if it was really useful to have each segment of a line painted by different colour. If this is a case why not use segments() directly? And probably the same applies to lwd, where it would be also strange if each segment was different line width?
