In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through.
Warning level 3 was used: -Wimplicit-fallthrough=3
Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find.
This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
