[Message part 1 (text/plain, inline)]

This is the part where you use make-lzip-input-port/compressed:

>  (define (compressed-port compression input)
> -  "Return an input port where INPUT is decompressed according to COMPRESSION,
> +  "Return an input port where INPUT is compressed according to COMPRESSION,
>  a symbol such as 'xz."
>    (match compression
>      ((or #f 'none) (values input '()))
>      ('bzip2        (filtered-port `(,%bzip2 "-c") input))
>      ('xz           (filtered-port `(,%xz "-c") input))
>      ('gzip         (filtered-port `(,%gzip "-c") input))
> -    (else          (error "unsupported compression scheme" compression))))
> +    ('lzip         (values (lzip-port 'make-lzip-input-port/compressed input)
> +                           '()))
> +    (_             (error "unsupported compression scheme" compression))))

So why not doing like for the others?
