Ahhh, yes, the escape. It works perfectly now. Awsome. of course, i don't
use zsh.. but maybe i should? I'll have to look into it.

Also, i thought there was some character that would convince echo -n to
echo an escape without you actually having to enter a literal one?
Maybe i'm dreaming?

Thanks for the info though - pretty much the same as the patch, without
all the work :)
