If you don't get the echo area to return to one line height, you're
not executing the recipe correctly, or perhaps you've customized
`resize-minibuffer-window-exactly' to nil.

First, why is *any* permanent motion OK?  If you want to push priority
down to zero or unassign yourself from the bug, that's one thing, but
but this is not backward compatible (assuming default settings), and
there's no specification that says this is desirable behavior or what
to expect in slightly different situations.

FWIW, I'm getting desired behavior in this XEmacs, `XEmacs 21.5
(beta28) "fuki" 2785829fe37c [Lucid] (x86_64-unknown-linux, Mule) of
Thu Mar 13 2008 on uwakimon' [ie, built immediately after your patch
was committed], in a TTY.

I'm getting the buggy behavior on Mac OS X in `XEmacs 21.5 (beta28)
"fuki" f4eb31866c38+ [Lucid] (powerpc-apple-darwin8.11.0, Mule) of Mon
Apr 7 2008 on chibi.local' on Apple's X server.  XEmacs is up to date
to 279739019e5c.
