RE: Documentation for car and cdr

[Drew Adams]

    a righteous hacker (fledgling or otherwise) would happily snort
    the challenging docstring like the gateway drug it is, disappear
    for a few days imbibing more in-depth documentation, and reappear
    later wielding `M-x report-emacs-bug' on those bits, instead (if
    need be).
