Subject: [PATCH] GCC7: fixes for -Wimplicit-fallthrough expected regexes

It turns out GCC7 adds a useful warning and does fancy things like
parsing your comments to work out that you intended to do the fallthrough.
There's a few places where we don't match the regex. Fix them, as it's
harmless to do so.

Found by building on Fedora Rawhide in Travis.
