D12416: revert: ask user to confirm before tracking new file when interactive

REVISION SUMMARY
  If interactively reverting from a commit with `hg revert -i -r`, we
  would unconditionally add files from that commit that are not already
  tracked in the working copy. We have prompts for adding back files
  removed in the working copy, but that's specific to such files and
  does not apply to adding files from another revision.
