The space before the  was preferred once upon a time, because prior to Netscape Navigator 4.0, browsers did not recognize the   as a separate token. They would interpret  as a   tag instead of a   tag with a. Since there is no such thing as a  tag, the browser would throw an error.

Since it's highly unlikely that anyone is still using a Netscape Navigator, let alone a version prior to 4.0, I prefer no space before.
