The only situation I can think of where it's not appropriate to have a space _after_ the ref is when there's a string of multiple references grouped together. What situations are you thinking of?
When the next character is a period or comma.
Most style guides of which I'm aware say that superscripts should be placed after a period or comma, not before it. That looks better to me as well.
And Wikipedia's style guide is one such: http://en.wikipedia.org/wiki/Wikipedia:Footnotes#Where_to_place_ref_tags Apparently based on the Chicago Manual of Style.
I see now that there's one other situation where there's no space after the </ref> tag; when it has a dash following it. I expect that's a fairly rare occurrence.
