Single quotes and double quotes are escaped when used with geshifilter

When used together with geshifilter, i get this

if ($boolean == TRUE) {
echo "GOOD";
}
else {
echo "FALSE";
}

instead of

if ($boolean == TRUE) {
echo "GOOD"
}
else {
echo "FALSE"
}

I entered "code" in the "ignore tag" textbox provided in the settings page of pearwiki_filter but it doesnt seem to ignore the code tag.
