    Yes, and a 0 value is returned.
    IOW, asking for an unsigned number (in the format string)
    and getting "-123" does return 0.

    What should it do?
    This function can't return -EINPUTERROR or -EILSEQ.
    (since it's after feature-freeze :)
    And the original problem was that a leading '-' sign on a
    signed number (!) caused a return of 0. At least that is fixed.

    So now the problem (?) is that a '-' sign on an unsigned number
    returns 0. We can always add a big printk() there that
    something is foul. Other ideas?
