I think that functions like ADD-RUCKSACK-ROOT and RUCKSACK-ROOTS should
not be called very often in 'normal' user code.  So it's probably not worth
it to create separate versions that give a default for one of the arguments.

If you do happen to call them very often in your program, you can always
create your own special versions.  But I don't think it's a good idea to
add them to Rucksack.
