This Eblock (and another in .h generator) didn't have a corresponding Sblock. 
When blocks just adjusted indent_level, this wasn't terribly noticeable because
a) there wouldn't be a runtime error and b) -2 * ' ' = '' in python (so
formatting doesn't freak out).  That said, it's still a bug, because it means
the next Sblock will go to zero indentation (instead of 2).
