[Zope] Zope quotes cookie values...

Hello, I wonder why ZPublisher/HTTPResponse.py adds double quotes to cookie values when creating the Set-Cookie HTTP header (see function _cookie_list) ? Browsers (Firefox at least) seem to consider these quotes as part of the value which can be problematic. Recently I had to patch HTTPResponse.py to remove the quotes because I wanted to set a session cookie for PHP from Zope (if someone's interested I'll explain why ;-) and PHP would not understand the cookie with the double quotes... Should I submit a patch to the maintainers ? Oscar Figueiredo
