OK, that is applied. So now, if the region is contained within a src
block, then it will be inherited by the language major mode edit
buffer. One consequence is that commands like M-; (comment-region) and
C-M-\ (indent-region) can be called with their native effects from a src
block in the Org buffer; see example below.
