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?
