I'd be happy to contribute it, though it's merely a slight
modification of a snippet I found on the web years ago, most probably
http://web.archive.org/web/20071128072321/http://blog.lathi.net/articles/2007/11/07/sharing-the-mac-clipboard-with-emacs
.  Is this code trivial enough that we needn't be concerned about
copyright issues?

Also, I see that xclip.el resides in the GNU ELPA repository.  Since
it's likely that many people using Emacs in -nw mode would like to
integrate Emacs kill and yank operations with their operating systems'
clipboards, I wonder if it would be worthwhile for some or all of
xclip.el's functionality to move into the core.  We could do this by
including a few simple wrapper functions such as the above to provide
interfaces to xclip, pbcopy/pbpaste, and whatever Windows equivalent
may exist, and mentioning those functions' existence in
interprogram-cut-function's and interprogram-paste-function's
docstrings.
