Changes (by simonpj):

  * priority:  normal => low
  * milestone:  7.2.1 => _|_


Comment:

 That's right. If you look at the discussion thread above we decided that
 allowing the space fixed your problem without making an invasive change to
 the libraries.  It's too liberal as you note, but it's not getting in
 anyone's way (as far as I know).  Until it does it's not worth the effort
 to fix it properly (unless someone wants to volunteer).

 Still, fair enough, it's still wrong so I'll leave it open with milestone
 bottom

 Simon
