Description
When inserting a node (e.g. during a code fix or refactoring), it would be very helpful if there were a way to say "ensure that there is a blank line following this node", rather than inserting one, since inserting one might result in a pair of blank lines. The determination of whether or not to actually insert a linebreak would be made in the printer.
