For the sake of humans reading introspection output, it is nice to have the name of implicit array types be recognizable as arrays of the underlying type. However, while this patch allows humans to skip from a command with return type "[123]" straight to the definition of type "123" without having to first inspect type "[123]", document that this shortcut should not be taken by client apps. This makes the resulting introspection string slightly larger by default (just over 200 bytes), but it's in the noise (less than 0.3% of the overall 70k size of 'query-qmp-capabilities').
