With ba9417470e we are assigning keyboard accelerator shortcuts to
menu items containing toggles. This PR makes the assignment to these
new items not occur on the first pass of doing so. This is less
disruptive in that first-letter shortcuts will remain the same from
prior versions, with only mid-word shortcuts possibly changing.
