DMD version = 2.070.0

I can't get errors nor warnings for fallthroughs except with final switches on enums (-w or -wi don't help).

Compiler versions:
- DMD64 D Compiler v2.082.0
- nightly at https://run.dlang.io/


import std.stdio;

void main() {
    int x = 0;
    switch (x) {
        case 0:
        case 1:
            writeln("woot");
            return;
        default:
    }
}

Actually I don't get fallthrough warnings for *any* switches.

So it seems to accept *empty* cases to fall through. I guess this is intended, then?

When compiling the initial example I get:

test.d(18): Error: switch case fallthrough - use 'goto case;' if intended


This seems to have been fixed

The problem is that with -version=bad, it incorrectly raises an error about missing a return statement or assert(0). That's still the case.

Here's a reduced example:
```
// accepts valid
int a()
{
    while (1)
    {
        switch (0)
        {
            case 0: // < implicit fallthrough
            default: continue;
        }
    }
}

// rejects valid
int b()
{
    while (1)
    {
        switch (0)
        {
            case 0: goto default; // < explicit fallthrough
            default: continue;
        }
    }
}
```
