display issues / line wrapping

Current trunk has issues to do proper line arrangements immediately; I
noticed the problem viewing Info pages and during query-replace.  Here
is the query-replace example:

After half a second Emacs corrects the display on it's own and the
buffer looked as follows (sometimes the weird display stays until the
next C-l or editing happens); here is the correct display:

I forgot to mention that I'm using

This is a bug already reported several times and apparently related to
partially visible lines and a non-zero `scroll-conservatively'. It seems
to be caused by a change to xdisp.c by Richard on 2002-07-07. I've seen
it happen in W95, W2K and RedHat GNU/Linux 7.2, but I suppose it happens
in all platforms.

There's indeed a bug, but I believe it only occurs if you set
scroll-conservatively to something larger than 1 (which you would
have done if you had read the docstring carefully.  I agree that it's
not necessarily obvious, tho).
