Right, we should be applying this GNU extension to --time=mtime also.
I.e. sorting when not displaying time (-l not specified),
and no other sorting specific option is used.

The proposed fix wouldn't work as time_mtime is the default,
so we'd be sorting by mtime rather than name by default.

I'll apply the attached later to address this.

Marking this as done.
