revert: accept just -I/-X without paths or -a/-i (issue4592)

'hg revert -I foo' currently fails with

  abort: no files or directories specified
  (use --all to revert all files, or 'hg update 1' to update)

It doesn't seem intentional that -I/-X without other paths or
--all/--interactive should fail, and it doesn't seem that harmful to
allow it either, so let's just do that.
