At the latest f2f, the WG decided that it wasn't a burden to require
no whitespace between "+" and "n", and so I've amended the spec
accordingly.  (Or rather, I'm trying to at the moment - preprocessing
errors are preventing me from uploading a draft right now, but they'll
be solved shortly.)

This removes any possibility of having to handle more annoying cases
in the name of "consistency".
