Subject: (adjust_after_replace): Don't add combining bytes to
X-Git-Tag: emacs-20.4~1737
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=8bedbe9dc24e2b2d170eaa4f23f7477f07d1ba75;p=emacs.git

(adjust_after_replace): Don't add combining bytes to
the args given to adjust_point.  Handle correctly the case that
there are both before and after combining bytes.
(replace_range): Likewise.
