;;; Change Log:
-;;; Changes before those recorded in ChangeLog:
-
-;;; Revision 1.4 92/09/14 16:26:02 liberte
-;;; Added prefix args to isearch-forward, etc. to switch between
-;;; string and regular expression searching.
-;;; Added some support for lemacs.
-;;; Added general isearch-highlight option - but only for lemacs so far.
-;;; Added support for frame switching in emacs 19.
-;;; Added word search option to isearch-edit-string.
-;;; Renamed isearch-quit to isearch-abort.
-;;; Numerous changes to comments and doc strings.
-;;;
-;;; Revision 1.3 92/06/29 13:10:08 liberte
-;;; Moved modal isearch-mode handling into isearch-mode.
-;;; Got rid of buffer-local isearch variables.
-;;; isearch-edit-string used by ring adjustments, completion, and
-;;; nonincremental searching. C-s and C-r are additional exit commands.
-;;; Renamed all regex to regexp.
-;;; Got rid of found-start and found-point globals.
-;;; Generalized handling of upper-case chars.
-
-;;; Revision 1.2 92/05/27 11:33:57 liberte
-;;; Emacs version 19 has a search ring, which is supported here.
-;;; Other fixes found in the version 19 isearch are included here.
-;;;
-;;; Also see variables search-caps-disable-folding,
-;;; search-nonincremental-instead, search-whitespace-regexp, and
-;;; commands isearch-toggle-regexp, isearch-edit-string.
-;;;
-;;; semi-modal isearching is supported.
-
-;;; Changes for 1.1
-;;; 3/18/92 Fixed invalid-regexp.
-;;; 3/18/92 Fixed yanking in regexps.
