These two examples are not equivalent.  In one, you're listing multiple
cases on a single line with the associated code following it.  In the
other, you're listing cases separately and letting the lack of a break
cause it to fail over to the next -- which leads to a very unintuitive
set of code.  Why not just employ your list of cases for the same
resulting code on one line?  That works just fine.
