Agreed, and the second one is how I prefer to format my C code too.

The two are not mutually exclusive. Indenting the continuation tackles 
the "silent bug" issue, while choosing where to place the operator is 
purely a readability issue - hence I prefer the second of your examples 
... it addresses both problems from my POV.

However, that doesn't answer my question of when a line consisting of 
just "+ expr" is a useful thing.
