I saw a similar comment in builtin-commands.lisp.  However, there's
something else going on, I suspect, because while the OS X binary
running under Apple X11 exhibits this double-RET problem, the same
binary displaying on Xorg on my workstation (tunnelled over ssh) does
not have the same problem.

(I think the XXX comment doesn't apply in any case, because the
EXPRESSION presentation type we ACCEPT in the listener has
:PRESERVE-WHITESPACE T in its options.  Still, it's possible that
something in there is causing a problem...)

Cheers,
