It partially supports yet another usage

  SU_CMD = eval sudo -E # see also ports/146816

That doesn't prepend sh(1) in COMMAND unlike su(1).

Note, `-E' is important. sudo(8) unlike su(1) resets environment by
default unless one adds !env_reset to etc/sudoers.

  $ FOO=foo sudo sh -c 'echo $FOO'
  $ FOO=foo su root -c 'echo $FOO'
  foo
