Formatter: No spaces around '=' in @property lines.

Before:
@property(assign, getter = isEditable) BOOL editable;

Now:
@property(assign, getter=isEditable) BOOL editable;

It'd be nice if some Apple person could let me know if spaces are preferred
around '=' in @synthesize lines (see FIXME in the test).
