IMO, showing the values in parentheses makes the description
potentially confusing.  E.g., for this description:

  "Only if wider than window (long)"

I needed to stare at it for some time before I realized that the
"(long)" part shows the underlying Lisp value.

AFAIK, we don't normally show values in parentheses like that.  Why is
it a good idea in this case (or at all)?
