Deletes text between start and end.
The order of start and end is not actually relevant; @delete will reorder them.
This function actually emits the “delete-range” signal, and the default handler of that signal deletes the text. Because the buffer
is modified, all outstanding iterators become invalid after calling this function; however, the start and end
will be re-initialized to point to the location where text was deleted.
