Why are our bind messages to wl_registry erroring out?

15:19 < daniels> yeah, wl_registry_bind is a special case - i think it's the 
                 one non-autogenerated marshaller we have
15:32 < daniels> actually no, sorry, i'm lying through my teeth
15:32 < daniels> it's no longer autogenerated
15:32 < daniels> but the parser expands new_id to interface + version + id
15:33 < daniels> it used to be hand-written, but is now autogenerated
15:33 < daniels>
16:28 < jekstrand> dan_b: It is a somewhat-special case.  Basically, every time 
                   there's a new_id that does not have any type information 
                   specified, two aditional pieces of information (interface 
                   name and version) get added.
16:29 < jekstrand> dan_b: That really should be documented, but it's not.  I 
                   had to grep through the scanner.c file to find it all.

Armed with this additional info the fix was fairly straightforward: I augmented the XML parsing/protocol generation to stick an additional pair of arguments into each message that contains a new_id and no interface.

Thanks to both daniels and jekstrand on irc for clearing it up.
