How about a warning for things like "if (...) ;"?

[CVI-User]

I'd really appreciate a warning for "empty bodies" or whatever it is called, i.e. things like

for(...);
while(...);
if(...);

 If written like

if(...) { };

 it is OK.

Only useful for if (...) else constructs, because there's too much code that legitimately uses null statements (empty blocks) in while or for loops.

Also note that you should not place a semicolon after the constructs shown, if (condition) {}; else {} is actually invalid syntax (that's different from struct/enums - but there the braces don't embrace a block).
