Hmm, interesting idea.  To be consistent, we should add spaces around 
all such items in the manual.  (that's easily done with sed, so no 
worries about that)

Basically, we'd consider \override Context.PropertyName  to be an 
unmentioned (or rare mentioned) hack, just like we current treat 
\relative { ... }

What do people here think?
