Would be useful, for readability purposes, to be able sort entries according the indicators appended by -F/--classify. A WORD called class could be added to "--sort" for this purpose.
In addition to that, it would be useful to have an option which forced
the extra entries printed by -a/-A, to be displayed after the rest of
the normal entries, and be sorted separately from them.
>From the man entry:
```
-F, --classify
append indicator (one of */=>@|) to entries
```
