Now that we're on the topic, I think bash does this a little better. If you have an

bash: ./foo: /bin/foo: bad interpreter: No such file or directory

Maybe this could be improved with zsh?

That doesn't really work for escape sequences now does it? For example, on
this machine, my prompt under script is shown in less like this:

^MESC[m^OESC[mESC[mESC[Jkuori% ESC[Kls^M

That sed removes the ^M and escapes, but what it leaves behind is 

[m[m[m[Jkuori% [K
