Extra comma appears at the end when displaying the terms for a node

I've done some research over this. I think that there is a logic error inside template.php. Line 340 retrieves all vocabularies for a content type. Let's say that the blog type has vocabularies a, b, and c. In the foreach loop through lines 342-357, for each vocabulary the list of terms associated for this vocabulary and the particular node is retrieved. Let's say that we retrieve terms x, y for vocabulary b. The if check at line 354 would return ', ', because the b vocabulary is not the last one in the list of vocabularies (remember, a, b, and c), although it's not associated with vocabulary c, so we should get a '' here. What we need is to check if the vocabulary is the last of the ones that this particular node is associated to and not to all of the vocabularies.

I currently cannot propose a solution, as it's 2:11am and I must go to bed. :-)

Thanks. Latest dev version works fine.
