Commit 04a759c8 authored by Jim Blandy's avatar Jim Blandy

The text property routines can now modify buffers other

	than the current one.
	* insdel.c (modify_region): New argument BUFFER.  Select that
	buffer while we prepare for the modification, and switch back when
	we're done.
	* textprop.c (add_properties, remove_properties): Pass
	the buffer being modified as the first argument to modify_region.
	* editfns.c (Fsubst_char_in_region, Ftranslate_region): Pass the
	current_buffer as the first argument to modify_region.
	* casefiddle.c (casify_region): Same.
