I don't know of any use-case where you actually want to use such an if
statement. Would you ever allow this to pass a human code-review?:

if (bVal)

    doSomething();

Btw this could also have been generated by some template mixin, don't
you want to be warned in such a case? I sure do.

But it can be a source of bugs.

This is a very specific situation that could be handled unless it is
too complex to mess with the lexer. If there's an if statement which
isn't followed by a block but is followed by a blank line emit a
warning. Sounds simple enough to me.
