 I think it's worth adding '-p' to rc (which would not import
functions from the environment) just to make rc shell scripts
more reliable in the face of random users using them. I know
that I've been starting all my scripts with something that
clears out the defined functions, but it's not foolproof;
'-p' would be better and more convenient. Never allowing
'fn' and 'builtin' to be redefined as functions would
probably also suffice, but I'd prefer '-p'.
