Michael Kifer 50a07e1856 2002-01-07 Michael Kifer <kifer@cs.stonybrook.edu> 
* viper-init.el (viper-cond-compile-for-xemacs-or-emacs):
	new macro that replaces viper-emacs-p and viper-xemacs-p in many
	cases. Used to reduce the number of warnings.

	* viper-cmd.el: use viper-cond-compile-for-xemacs-or-emacs.
	(viper-standard-value): moved here from viper.el.
	(viper-set-unread-command-events): moved to viper-util.el
	(viper-check-minibuffer-overlay): make sure
	viper-minibuffer-overlay is moved to cover the entire input field.

	* viper-util.el:  use viper-cond-compile-for-xemacs-or-emacs.
	(viper-read-key-sequence, viper-set-unread-command-events,
	viper-char-symbol-sequence-p, viper-char-array-p): moved here.

	* viper-ex.el: use viper-cond-compile-for-xemacs-or-emacs.

	* viper-keym.el: use viper-cond-compile-for-xemacs-or-emacs.

	* viper-mous.el: use viper-cond-compile-for-xemacs-or-emacs.

	* viper-macs.el (viper-char-array-p, viper-char-symbol-sequence-p,
	viper-event-vector-p): moved to viper-util.el

	* viper.el (viper-standard-value): moved to viper-cmd.el.
	Use viper-cond-compile-for-xemacs-or-emacs.

	* ediff-help.el: use ediff-cond-compile-for-xemacs-or-emacs.

	* ediff-hook.el: use ediff-cond-compile-for-xemacs-or-emacs.

	* ediff-init.el (ediff-cond-compile-for-xemacs-or-emacs): new
	macro designed to be used in many places where ediff-emacs-p or
	ediff-xemacs-p was previously used. Reduces the number of
	warnings.
	Use ediff-cond-compile-for-xemacs-or-emacs in many places in lieue
	of ediff-xemacs-p.
	(ediff-make-current-diff-overlay, ediff-highlight-diff-in-one-buffer,
	ediff-convert-fine-diffs-to-overlays, ediff-empty-diff-region-p,
	ediff-whitespace-diff-region-p, ediff-get-region-contents):
	moved to ediff-util.el.
	(ediff-event-key): moved here.

	* ediff-merge.el: got rid of unreferenced variables.

	* ediff-mult.el: use ediff-cond-compile-for-xemacs-or-emacs.

	* ediff-util.el: use ediff-cond-compile-for-xemacs-or-emacs.
	(ediff-cleanup-mess): improved the way windows are set up after
	quitting ediff.
	(ediff-janitor): use ediff-dispose-of-variant-according-to-user.
	(ediff-dispose-of-variant-according-to-user): new function
	designed to be smarter and also understands indirect buffers.
	(ediff-highlight-diff-in-one-buffer,
	ediff-unhighlight-diff-in-one-buffer,
	ediff-unhighlight-diffs-totally-in-one-buffer,
	ediff-highlight-diff, ediff-highlight-diff,
	ediff-unhighlight-diff, ediff-unhighlight-diffs-totally,
	ediff-empty-diff-region-p, ediff-whitespace-diff-region-p,
	ediff-get-region-contents, ediff-make-current-diff-overlay):
	moved here.
	(ediff-format-bindings-of): new function by Hannu Koivisto
	<azure@iki.fi>.
	(ediff-setup): make sure the merge buffer is always widened and
	modifiable.

	result of a merge into a file visited by another buffer.
	(ediff-arrange-autosave-in-merge-jobs): check if the merge file
	is visited by another buffer and ask to save/delete that buffer.
	(ediff-verify-file-merge-buffer): new function to do the above.

	* ediff-vers.el: load ediff-init.el at compile time.

	* ediff-wind.el: use ediff-cond-compile-for-xemacs-or-emacs.

	* ediff.el (ediff-windows, ediff-regions-wordwise,
	ediff-regions-linewise): use indirect buffers to improve
	robustness and make it possible to compare regions of the same
	buffer (even overlapping regions).
	(ediff-clone-buffer-for-region-comparison,
	ediff-clone-buffer-for-window-comparison): new functions.
	(ediff-files-internal): refuse to compare identical files.
	(ediff-regions-internal): get rid of the warning about comparing
	regions of the same buffer.

	* ediff-diff.el (ediff-convert-fine-diffs-to-overlays): moved here.
	Plus the following fixes courtesy of Dave Love:
	Doc fixes.
	(ediff-word-1): Use word class and move - to the
	front per regexp documentation.
	(ediff-wordify): Bind forward-word-function outside loop.
	(ediff-copy-to-buffer): Use insert-buffer-substring rather than
	consing buffer contents.
