I'm not sure the first few cases here actually add much in
the way of readablity.

This 'rule' is very 'vague' deliberately as sometimes it makes sense
and sometimes it really doesn't.

One nice convention is to have ret on it's own line when it is the
value returned by the function (it doesn't logically group with anything
else). Having that one last is also nice to see (so I like your final
change more than the others!)
