Thanks Eli.  Sorry about that, I will try to be more careful in the

It just occurred to me that this change will break backward
comparability for those who bind some key to the `recenter' command,
since now the second argument will always be nil and thus won't
redisplay.  Should we also change the interactive form of recenter to
use "p" for the second argument?  That way the second arg is never nil
when used interactively.
