Problem is that I do not see that `S' for sorting in
`tabulated-list-mode' runs any hook.
Do you think that is error, and that hook shall be run after sorting?
If I place my function to highlight stuff on the end of
`tabulated-list-sort' then it works well.
I think that `tabulated-list-sort' shall run the derived mode's hook.
