When I edit code, I sometimes see it mis-fontified when I'm half-way
through editing a syntactic construct.  Unlike some others, I don't
expect font-lock to do a 110% perfect job in every situation, and
prefer a casual M-o M-o to having font-lock definition for a mode
perfected to a point where it becomes unbearably sluggish.
