Sorry for the unreasonably delay in responding to this message.  I've
finally come up with something acceptable:

[0001-Add-command-to-copy-contents-in-a-diff-mode-buffer.patch (text/x-patch, attachment)]

This will also copy text between hunks.  I've tested it a bit, but I am
sure someone else here might find some edge-cases.
