Precedence: bulk

Instead of dancing around all these prefixes, why not just be
explicit about it. There are three cases:

  chdev add abcd	# add 'abcd' to the current set
  chdev del abcd	# remove 'abcd' from the current set
  chdev abcd		# 'abcd' becomes the absolute set

No ambiguities, and dead simple to parse.
