bug#29156: 25.3; eshell/kill does not understand -<signal>, [PATCH] Make eshell/kill handle -<signal> and -<SIGNALNAME>

[Noam Postavsky]

Thanks, do you have copyright assignment for Emacs? (the change is small
enough to install regardless, I'm asking just to know if it should be
marked as a tiny change).

A couple more minor nitpicks:

>      * doc/misc/eshell.texi (kill): Update docs to reflect new
>      function behaviour
>      * etc/NEWS: Mention new eshell/kill behaviour

Missing periods here.

> +          (setq signum (intern (substring arg 1 (length arg))))))

That could be just (substring arg 1)

P.S. don't worry about the forwarding thing, it happens often enough
that I've written an Emacs command to mostly automate it.
