breaks thunderbird-bin compatibility, as the directory specified there is only

Quick and dirty fix :
---------------------------------------------------------------------
173,175d172
< # Trim -bin from ${zero} for the sake of xremote -a programname
< zero=${zero%-bin}
<

> if [[ $zero == thunderbird-bin ]]; then
> fgrep -q '"0.7"' /opt/thunderbird/defaults/pref/thunderbird.js \
> && zero=Thunderbird
> fi
>
> # Trim -bin from ${zero} for the sake of xremote -a programname
> zero=${zero%-bin}
