Make parent term page display only parent term name

Currently, when tids are combined on the url of a vocabulary's parent term (taxonomy/term/10+11+12 where 10 is the parent term), the taxonomy system has the annoying habit of lumping together all the child term names in the title of the parent term page, although in comma separated fashion. This is bad, but it gets worse when *all* the tids are combined in this url.

It would be a great usability improvement if only the parent term's name is displayed as the page title. A good example of this implementation is the taxonomy_vocabulary module by Mike Carter that combines the nodes of all the tids for a vocab and lists it on a page, but only shows the vocab title on that page.
