===Numlock-bypass release for navigation keys in scancode-set 1 and 2===
For 102-keyboard navigation-keys and PrtScr (originally these were only on the numeric pad of the IBM 83/84-key model F), a make/break-pair of an 'ignore num-lock' scancode is added around the base scancode make/break-pair if num-lock is active. This is as described in the IBM technical references, and also the exact behaviour for v1.4 in all cases. However, in v1.7 to v2.1, the break-part of the 'ignore num-lock' scancode is inserted prematurely, before the next make-scancode if another non-navigation key is pressed while the navigation key is still being held. This enables keys on the numpad to be pressed when any navigation key is being held, respecting the currently selected num-lock state.
