Incidentally, the MARK=CURSOR "magick" doesn't seem to be needed any
more with the most recent revision of narrow-to-region.  However, if
you remove that, then the retrieved history will *replace* whatever
text starts out in the region between MARK and CURSOR.   (This is
consistent with what bracketed-paste does, if that matters.)
