This is not actually a bug, per se.  It is a side effect of counting lines
where the size of a line is not a constant.

How about this: when a message is selected, compare window-displayed-height 
to window-height.  If they differ significantly enough, shrink or enlarge
the summary buffer window so that it displays the correct number of summary 
lines.
