private isn't recognized as a keyword by the IDE's editor

[JaroslavTulach]

While investigating better behavior of type classes I created following program:

from Standard.Base import all
import Standard.Visualization

type R
    private V a:Text i:Integer

    as_text self = self
    as_both self = self
    as_int self = self

Text.from (that:R) = that.a
Integer.from (that:R) = that.i

main =
    n = R.V "Hi" 3
    t1 = n.as_text
    b2 = n.as_both
    i3 = n.as_int

and it renders incorrectly:

private isn't rendered as keyword.
