Hmmm I was hoping there would be a more natural way to do it. For example, if you actually try to call the first function with all arguments:
lm(formula=dist~speed, digits=3, data=cars) R will match whatever it can, and give you a warning with the names of remaining unmatched arguments. The only thing I really need is instead of a warning take these arguments and pass them on to the next function.
