Fixes incorrect indentation we got previously when they were used in a
statement context.

So you now get
enum A { a = 2,
         b = 3,
       };

This will allow much faster indenting of selected areas as the state
doesn't have to be checked again for every line.

Keep more information by using enter() instead of turnInto() when moving
from a *_start to *_open.
