Link to "Source" is not separate by whitespace from preceding content

This is annoying when you try to visually mark/select a word, e.g. if you try to select openTempFile in Firefox (with double a click) the "Source" link will get selected, too.

I'm not an expert, but it seems to me that the Source link should be in a separate block-level element (e.g. div), and that should solve the problem.

Adding a whitespace would be a dirty hack.
