Subject: fix(column): add truncated width during estimation for 'statuscolumn'

Problem:    Estimated 'statuscolumn' width estimated is not properly used,
            executing the `w_redr_statuscol` path unnecessarily.
Solution:   Adjust `w_nrwidth` and 'statuscolumn' width before anything
            is actually drawn in a `win_update()`.
