Ah colors.

The behavior that you see is entirely correct. As I said, the  in
the first case are interpreted as two occurrences of 'backquote'. In
particular, this means that with is outside of its scope and the rest
is dealt with as plain Scheme.

The second one is exactly what you'd get in Scheme code. Perhaps it's
confusing to use keyboard quotes for code in a document, especially
because the Latex books has such a long passage on quote marks. But
it is correct.
