Currently there is no way of doing this, because the code you see is
the result of a parse() and deparse() and I need the parse() step to
know where to insert output, i.e., where expressions are complete. I
have ideas about chunks where the code is exactly as in the source
file, but no time to implement them yet.

what you always can do is to write the code in a separate source file,
include that with, e.g., latex's listings package and do a source() on
it with echo=FALSE. If you want code and output mixed one needs to
parse() -> you loose the original formatting.
