Create new post form triggers a JS error in IE6/IE7

We need to comment/delete the following code in Blog.BlogScripts JS extension:

/*
Event.observe(form, "submit", function() {
form.action="${xwiki.getURL('_space.name', 'inline')}".replace(/space/, encodeURIComponent(form.entrySpace.value)).replace(/name_/, encodeURIComponent(form.entryTitle.value));
});
*/
