afcopy: some enhancements from Bryan's dotfiles This makes `afcopy` able to drop things in the clipboard over ssh. Wild stuff. See https://bitbucket.org/bcmills/dotfiles/src/101956eeb90160f1d225ae23c8e6566c9df91c5c/bin/clip?at=default&fileviewer=file-view-default for some details.

# This is broken into its own file on account of not being able to
# properly make opendiff-w bail when opendiff is unavailable.
