just for my own understanding: are you saying that the fact that the
minibuffer displays more than one line causes a re-centering of my
current buffer? why is that normal? if i M-: (message "a\nb\n"), should
i expect that my current buffer is recentered?  (it isn't).

(also, for the record, the message displayed by that custom set-message
does not span more than one line, as far as i can tell.)
