Subject: (isearch-edit-string): Save old point and
X-Git-Tag: emacs-pretest-23.0.90~11785
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=02b99a172e2127474b13a4bdddd8e339941313e4;p=emacs.git

(isearch-edit-string): Save old point and
isearch-other-end to old-point and old-other-end before reading
the search string from minibuffer.  After exiting minibuffer set
point to old-other-end if point and the search direction is the
same as before reading the search string.
(isearch-del-char): Don't set isearch-yank-flag to t.  Put point
to isearch-other-end.  Instead of isearch-search-and-update call
three functions isearch-search, isearch-push-state and isearch-update.
