;; Emacs used to count each multibyte character as several positions in the buffer,
;; so we had to use Emacs's chars-in-region to count characters. Since 20.3,
;; Emacs counts multibyte characters as 1 position. XEmacs has always been
;; counting each char as just one pos. So, now we can simply subtract beg from
;; end to determine the number of characters in a region.
