ls: `-v` flag

[obiwac_gmail.com]

Summary

Add a -v flag for ls(1) which sorts entries following a natural ordering using strverscmp(3) (e.g. "bloem1 bloem9 bloem10" as opposed to "bloem1 bloem10 bloem9").

Update manual page for ls(1).

Add test for ls -v.

Test Plan

Tested through the tests I wrote.

I forgot a comma here when reordering.

One more comment about the manpage. Did you run "mandoc -Tlint" over it?

This needs a line break after the sentence stop.

I have not, I didn't know about that, thanks for pointing me to it! I'll fix that in a bit. May I fix all the "STYLE: useless macro: Tn" errors or do I ignore those?

I suggest you do this in a separate commit to not bloat this one too much.
That way, we can separate individual changes easier and the review time in also reduced as people can focus on a single change.
