Fix "obvious" fall-through warnings

Browse Source 
This patch fixes the subset of -Wimplicit-fallthrough warnings that I
considered obvious.  In most cases it was obvious from context that
falling through was desired; here I added the appropriate comment.  In
a couple of cases it seemed clear that a "break" was missing.
