[plt-scheme] Return in Interactions pane

The paren matcher answers questions of the form "which opening paren
matches this closing one?". The answer can be either a specific paren,
or something that indicates there is no match. The REPL asks that
question when you hit return in a previous interaction. At the moment,
the paren matcher always indicates that there aren't any matching
parens, even when there are. That's why the repl doesn't bring down the
expressions anymore.
