Try catting it on linux console. It takes the garbage, overwrites it with ^Hs, then writes ... "its saddle and harness for price 1", then shifts cursor right (over 4 or `, depending on first block), then continues with "000 dollars". My trick does *not* work in Gnome Terminal (I've just verified it). You need actuall linux console, press ctrl-alt-F1 on most distros to get to one... but if you tell me what terminal you use, I can probably create terminal sequence that works there...
