Isearch used to decompose a composition of a character with a combining
accent and displaying them separately in the middle of a composition
in Emacs 23.  But as I see now in the latest version Isearch in the
middle of a composition doesn't decompose them.  It highlights the
matched character with still unmatched combining accent as a whole.
It seems the current behavior is better then earlier because it doesn't
change the displayed characters.  This is more WYSIWYG.
