In fact I see we seem to have checks for completely empty hrefs, but blanks 
might cause a problem. I tried putting some <a> tags into the splitting example 
that was causing Henning a problem, but that doesn't seem to make the links to 
disappear so if we are creating a spurious link it has to be more complicated. I 
wonder what happens if I can make the split happen in the middle of the link?
