I should never post before lunch: my hunger even affected the title.

You can't do cd et al. properly in the way I suggested, as rc does not keep
all of its state in the environment (specifically, it doesn't keep where it
is an a flow control construct, the input stack, $*, and $status). So, you
couldn't use a not-built-in command in an if () statement, couldn't use
it in a script, and couldn't find out if it worked or not.

I thought that we might at least salvage a non-builtin-in limit, but then
I realized that probably the most common use of limit is to set coredumpsize
to 0 in .rcrc.

Of course, we could have rc realize its entire state in the environment,
but I hear the wolves baying over in the es list, so I won't even
suggest this.
