Thank you for finding the time to do what I did not have the time to. (o8

As I have said several times on this list, this is well overdue.  Hopefuly 
the '-' tags can migrate their way out of Zope the way <!--# has.

I like!  I like it a lot!  This is, imho, quite an elegant solution to an 
ugly problem.

I know these two were considered 'minor' problems, and thus not given much 
attention, but they're just one more niggling problem that will no longer 
elicit the same old newbie questions to this list.

Have a better one,
