;;{{{ Introduction
;;; Expand-region extends the region, based on the syntax of the text in the buffer,
;;; upon each successive invocation of er/expand-region. Correspondingly,
;;; er/contract-region shrinks the region. Note that point is moved to the
;;; start of the newly expanded or contracted region.
