bug#6192: 24.0.50; eldoc-mode: unexpected recentering

I always had - how else can you do it?  But the problems only started
after the series of changes following the release of Emacs 22.  I was
mainly annoyed by the continuous resizing of the echo area, especially
when eldoc tries to analyze doc-strings or comments.  So I first wrote
some workaround until I found out that customizing the faces suffices.

Meanwhile I show eldoc-strings either in the header-line, a separate
window, or in a tooltip - but none of them work satisfactorily :-(

Anyway: The recentering is a misbehavior which should not occur.  Does
Emacs restore the old situation when the echo area sizes back?
