`//` in continuation lines aren't reported as problems

/// blah blah blah
// <- notice how there are 2 `/`s

This should be a problem and be autoformattable.

Huh, I hadn't considered this as a possibility. The contract for how to interpret discontiguous doc comment lines seems under-specified, and now that's got me thinking about what the right way to handle it would be...

If it's a typo, then we'd ideally want to auto-correct, or maybe just generate a warning.

What if it was intentional, though? A normal comment between doc comments has the same effect as commenting out code, so someone could use this as a clever way to annotate doc comments. In that case, I think any attempt to resituate it would be destructive.
