bug#16150: Emacs not deleting lock files when system-name is set to nil

When setting system-name to nil (should that be allowed?), Emacs forgets
how to delete the lock files '.#.*' and all subsequent startups complain
about lockups by old dead PIDs.

From what I get, either system-name should not be allowed to set as nil or
file locks should be still deleted on exists because they still have
usernames in the aliases.

I think this is a "don't do that, then".
If Emacs fails to set system-name, that is a bug.
If you actively set system-name to nil, that's just shooting yourself
in the foot.
Why did you want to do that, and what made you think it would work?

Ehh.. just because one could do that? And setting it to nil shoots no
errors during the --init. This gives enough assumptions, I believe ;)

You can do a lot of strange things with Emacs.
You could rebind M-x to ignore, have fun if that's what you want to do. :)

The importance of 'M-x' is significant.
I don't see any rudimentary usage of 'system-name' while one edits file or
even plays games. Does it really need to be aware of 'host-name'? Let's be
honest, if host-name is that important to Emacs, why did I get everything
working except the lock file deletions?

Quite likely because you didn't really test *everything*. So it's a
ticking time bomb.
