Peter, what do you think about pushing the query buffer onto the history
stack at execution time, any time it's a multiline query? That way,
after the above sequence, you'd have:

(1) select *
(2) \x
(3) from foo;
(4) select * 
    from foo;

Yeah, this wastes a history slot, but it does solve the problem. It's also
dead simple to code. ;-)

BTW, the behavior in bash for multiline interactive entered commands
is to concatenate them into a single line and dump them in the history,
replacing the individual parts.  The individual parts are in the history
while you're at the secondary prompt, then go away after execution. In
psql, we'd probably just lose interstitial metacommands.
