I probably should have added to the commit message that this
documentation is intentionally minimal, because it's not intended for
people creating properties; that should go in API documentation, I think.

I don't really understand the comment on the next line (since it seems
that no : is added to XPROPERTY by Xapian), but I guess we should
probably be consistent. Maybe Jani can explain the comment?
