-/**
- * Record undo information - call with the current cursor and the 'other
- * end' of the range of changed paragraphs. So we give an inclusive range.
- * This is called before you make the changes to the paragraph, and it
- * will record the original information of the paragraphs in the undo stack.
- *
- * FIXME: We need something to record undo in partial grids for mathed.
- * Right now we use recordUndoInset if more than one cell is changed,
- * but that puts the cursor in front of the inset after undo. We would need
- * something like
- * recordUndoGrid(DocIterator & cur, UndoKind kind, idx_type from, idx_type to);
- * and store the cell information in class Undo.
