Ah, ok, I get it now. No, it's not that important, in fact, sometimes is automatically added when editors, especially anons, edit pages in visual mode (intead of source mode).

I usually replace that particular tag for the Template:Reflist if I came across it, and when I see that too many spaces are added in one edit (usually when having tags like this,, instead of  ) I remove the blank spaces, simply to reduce the number of bits the page consumes, but only if I come across them, I don't look for them.

Hope this answers your question :)
