[xemacs-hg @ 2003-08-02 08:42:10 by michaels] 2003-07-31 Mike Sperber <mike@xemacs.org> * isearch-mode.el (isearch-mode-help): (isearch-update): (isearch-done): (isearch-edit-string): Change the way window configurations are handled: Formerly, the code would do `set-window-configuration' off `pre-command-hook' which isn't really allowed. (The old window-configuration code would quietly ignore this restriction.) Instead, save the window configuration only when someone asks for help, and restore afterwards, and otherwise leave it alone.
