State modifers

[iain <iain prettypeople org>]

This is probably a dumb question:

For a GdkEventKey is event->state set in the case where only the Shift
key is pressed? When I press the Shift key, I get a key press event
emitted, but event->state isn't set to anything. If the shift key and
another key is pressed, then event->state & GDK_SHIFT_MASK is true. 

Is this correct behaviour? If so, how do you detect when only the Shift
key is pressed?
