nim doc renders char as int when inside a const object

[GULPF]

Using nim doc on this file:

type O = object
    foo: char

const Z* = O(foo: 'c')

renders as Z = (foo: 99).
With nim doc0 it is rendered correctly.

Again because semConst removes all information from the const and after it evaluates the value 'c', all that is left is the 99.
