Hi,

I've patched cl-octave for SBCL. Tested on Mac OSX and Debian/Linux in SBCL 1.0.2.

Somehow, the return string of my octave on Mac OSX is different to that on Linux. I don't know whether it's the same on other's machine. Please refer to function find-number-string-from-end and get-as-number.

Here is the patch.
