[Zope-CMF] Base Href's

[HoYin Au]

    Is there a reason why CMF1.2 + ZPT inserts Base Hrefs that include 
the current filename with a trailing slash, such that if page1.html 
links to page2.html and vice versa, after a few clicks I have this 
resulting URL:

http://someserver/somepage/page1.html/page2.html/page1.html/page2.html/page1.html/page2.html/page1.html/page2.html/page1.html/page2.html/page1.html/page2.html/page1.html/page2.html/

?  Why not just use "http://someserver/somepage/"?
