Subject: [PATCH] Do not highlight in isearch widgets

As long as zle_highlight for the isearch region can't be applied
properly *after* zsh-syntax-highlighting is done it does not make
sense to apply any highlighting while isearch is active.

Otherwise its almost impossible to see the matched area.
