I have attached a new patch with a test named 
`test-ob/demarcate-block-split'.
Besides testing the duplication of switches and some header arguments, 
it also
shows that multi-line header arguments are not duplicated.

Whether this is a bug or a feature in `org-babel-demarcate-block' may be 
a
point of discussion. I have no real opinion.

The code of the 4 (should ...) forms in the test below the line
;; unduplicated multi-line header arguments:
feels a bit clumsy. Does Org have a function to extract the value that a 
particular
var-name has from the association list returned by 
`org-babel-get-src-block-info'?
