It just works that way <G>. Each level will process special characters so
if you just have the shell that's one level. Scripts, etc. require
additional characters for escaping since some of the characters are
stripped before they get it.
Or something like this. I used to know the technical explanation in detail
but I do remember you sometimes have to add additional escape characters.
