show, as, deferred, and hide aren't highlighted in newline without trailing space in previous line

[triallax]

I'm sorry if the title isn't very clear, but I couldn't come up with a better description. Here's an example:

// This works (minus sign represents space using ':set list')
import 'foo.dart' 
show Foo;
import 'bar.dart' 
hide Bar;
import 'baz.dart' 
as baz;
import 'bat.dart' 
deferred as bat;
export 'foo.dart' 
show Foo;
export 'bar.dart' 
hide Bar;

// This doesn't ('as' is still highlighted for some reason,
// perhaps because it's considered an operator)
import 'foo.dart'
show Foo;
import 'bar.dart'
hide Bar;
import 'baz.dart'
as baz;
import 'bat.dart'
deferred as bat;
export 'foo.dart'
show Foo;
export 'bar.dart'
hide Bar;

// This also doesn't work (even with trailing space)
import 
'foo.dart' show Foo;
import
'bar.dart' show Bar;
