It's exported if it's changed from the default.

The motivation for doing so was this little snippet:

    $ env - rc
    ; printenv
    prompt=; ^A

No point in cluttering the environment with a value that any
descendant rc process would default to anyway.  And since I'd just
invented the mechanism to export $version only if it's assigned to
(all 3 lines of code of it!), I thought I'd use it.

So in the dev version, we get this.

    $ env - rc
    ; printenv
    ; prompt=('rc$ ' '')
    rc$ printenv
    prompt=rc$ ^A

(And even PATH goes away if you build with `--disable-def-path'.)
