D-Bus Spec change: dashes in interface names

[Havoc Pennington]

Hi,

I did think of another issue, which is that many programming languages 
allow underscore but not hyphen in identifiers. I think that's also why 
dbus doesn't allow starting things with a number (if I remember right 
that it doesn't allow that).

Google turns up this:
http://java.sun.com/docs/books/jls/second_edition/html/packages.doc.html

I'd lean a bit toward leaving things as they are, I guess. Maybe docs 
similar to the above should be in the spec though.
