Title:
  sudo-rs does not work using 'watch', regular sudo works fine

Status in rust-sudo-rs package in Ubuntu:
  Fix Released

Bug description:
  I stumbled on this one because my normal sudo was silently replaced
  with sudo-rs, with no acknowledgement.

  I can reproduce this on 3 different hosts, so it's definitely not
  related to local configuration.

  Steps to reproduce:

  1. Log into a host with a clean shell
  2. Run the following `watch -n1 -c -d "sudo zpool status -v"`
  3. You will be prompted for the sudo password
  4. .... nothing, the command does not run, although the password was successfully accepted

  Now, oddly, ^C that command that seems to be running without output,
  and run the following:

  1. Log out
  2. Log back in (clean shell) 
  3. Run the following: `sudo zpool status -v`, this will work
  4. Now run the same command, but _prepend_ the previous 'watch' parameters, this will also work
  5. Log out, and back in
  6. Run step 4 alone. This will fail. 

  There appears to be some sort of shell or tty sanitization that's
  happening here, and running the initial 'sudo' command to 'warm' the
  shell, then re-running the same command under 'watch', seems to work.
  Running the full command ('watch' + 'sudo'), does not produce any
  output.
