Hello, Emacs maintainers.

The command copy-next-command-output copies the output of the next
command, and having used it for several months, I would like to suggest
this for Emacs core.  It doesn't appear to be part of Emacs.  I
typically bind this C-c u.

This code was provided by Stefan on this list or emacs-devel, so the
author should be changed accordingly (I haven't modified Stefan's code,
just used it).

Thoughts welcome as this is my first patch suggestion.  It could also be
put in a package in ELPA.  I have signed the paperwork.

Thanks in advance

Jeremy
