[O] [babel] code execution in commented lines

[Andreas Leha]

Hi all,

by now I learned not to call behaviour not meeting my expectations a
bug hastily....

So, here is my question:
Is it intended that code in commented lines gets executed during export?

# example: buggy, thus commented src_R{Sys.sleep(10) && stop("Here is a Bug")}

This kind of violates the I-quickly-comment-this-out style of fixing
broken parts of the document ;-)

Regards,
Andreas
