It's more-less clear how to write code for the "slow&complex" path using the existing =E2=80=98region-extract-function=E2=80=99 and a new fu= nction like =E2=80=98region-insert-function=E2=80=99 like I demonstrated with define-= advice for shell-command-on-region in the beginning of this thread (where specific =E2=80=98insert-rectangle=E2=80=99 should be replaced with =E2=80= =98region-insert-function=E2=80=99). What is not clear is how to distinguish "slow&complex" from the "fast-pat= h"? Maybe with a new arg REGION?
