Thx and sorry about not posting to the list, was a gmail mistake (i really
*need* to start with gnus..just to intimidating :))
wrapping in parens by marking the region kinda defeats the purpose sine the
original function i posted (in the original post) already wraps the marked
text in an orgmode block :)
thanks and sorry for PM
