copy: add experimental support for marking committed copies

The simplest way I'm aware of to mark a file as copied/moved after
committing is this:

  hg uncommit --keep <src> <dest>  # <src> needed for move, but not copy
  hg mv --after <src> <dest>
  hg amend

This patch teaches `hg copy` a `--at-rev` argument to simplify that
into:

  hg copy --after --at-rev . <src> <dest>

In addition to being simpler, it doesn't touch the working copy, so it
can easily be used even if the destination file has been modified in
the working copy.
