Good catch! Messages had been temporarily disabled, but I finished
adding a message declaration suffix (!) just before your mail came in.
In 2.3.1 your example will look like this.

menu usb # USB? support
USB_DEBUG
usb_options_legend!
USB_DEVICEFS USB_BANDWIDTH USB_LONG_TIMEOUT
usb_controllers_legend!
h:USB_UHCI? h:USB_UHCI_ALT? h:USB_OHCI?
...

The reason for this change in design is to make it easier to automatically
generate per-directory distributed symbols files. But the good thing about
it is that it simplifies the language -- I was able to remove three constructs
and only have to add back one.
