Hear hear - atoi() is inherently stupid.  There's a 'make syntax-check'
that we could turn on to prohibit all use of atoi(), but I don't know if
the code base is ready for that, so I'll save it for another patch on
another day.

Any reason you are still requiring decimal, or would it make more sense
to branch out and s/10/0/ in order to also accept hex?

At any rate, ACK to the patch.
