Just to be unambiguous, here is my proposal set in a monospace font:

switch (x) {
   case foo: {
   case bar:

(Hoping this doesn't get mangled in email.) Reasons I suggested this  

A) Actual statements end up indented 4 spaces, preventing excessive  
indent, and perhaps aiding readability in the no-brace case.
B) You can't end up with a brace at the same indent as the switch that  
doesn't actually close it; or two braces at the same indent level in a  

I think using a partial or half indent for case labels is not a wild  
or uncommon style. Some also use half-indents for goto labels, but no  
one seems to have a problem with leaving those unindented as far as I  
can tell.

That said, if no one prefers this to the status quo, we should stick  
to the current rule. But I don't think we should allow multiple  
different indent styles.
